1 Executive Summary
This report details the short circuit fault level calculations for the MV and LV
switchboards to be installed at Telecity’s new data centre AMS06 located in
Amsterdam.
The fault ratings of the switchboards are as follows:
Medium voltage switchgear: 20kA (rated short time withstand)
Low voltage switchgear: 50kA (rated short time withstand)
1.1 MV Systems
The Liander network maximum fault levels have been provided. As there are no
MV generators associated with the system the maximum fault level expected on
the MV switchboards is solely based upon the Liander network characteristics.
Operating Scenario Anticipated Fault Level Result
10kV Supply 8.75kA PASS
20kV Supply 10.47kA PASS
As demonstrated in the table above the maximum anticipated fault levels for the
network are lower than the rated withstand of the switchboards. Therefore the MV
switchboards are sufficiently rated.
Note: The fault levels in the table above have been provided by Liander. The
values in the ERACS model in section 6 are slightly higher (representing a more
stringent requirement). However the MV switchboards are adequately rated for
both conditions.

3 Network Overview
The following diagram at high level details the electrical network for the MV and
LV infrastructure of AMS06.
Following handover in 2015 the data centre will be supplied from the local
Liander network at 10kV. Due to the demand load growth in Amsterdam it is
expected that the network will be upgraded to 20kV once the data centre load
reaches 10MVA. Therefore as part of this calculation the following operating
scenarios have been modelled to determine the short-circuit fault current for
various system conditions including:
1. Fault current from a single transformer
a) 10kV Liander network voltage
b) 20kV Liander network voltage
2. Fault current from a single generator
3. Fault current from a transformer and generator operating in parallel
a) 10kV Liander network voltage
b) 20kV Liander network voltage

4 Utility Information
The following fault level data for both the 10kV and 20kV networks serving
AMS06 has been received from Liander on 7th April 2015.
Aansluiting 10 kV 20 kV
Minimale kortsluitstroom 7,82 kA 9,39 kA
Minimale kortsluitvermogen 142,2 MVA 341,7 MVA
Maximale kortsluitstroom 8,75 kA 10,47 kA
Maximaal kortsluitvermogen 159,0 MVA 380,9 MVA
5 Calculation Process
The fault levels have been calculated using ERACS. ERACS is a globally
recognised power system program. Arup subscribe to a yearly maintenance fee
thereby ensuring that the software is always up to date. For information on this
software refer to the appendices for the ERACS brochure. It should be noted that
it is not possible in Amtech to parallel multiple sources onto the same
switchboard. Also Amtech does not calculate ‘Making’ and ‘Breaking’ duties of
the circuit breakers, which is critical for sources operating in parallel. One of the
intended operating scenarios for AMS06 is for the transformer and generator to be
paralleled. Therefore to calculate the fault levels in this scenarios the alternative
ERACS software has been used to determine the maximum anticipated fault
levels at the AMS06 switchboards.
The generator contribution to fault levels has been modelled in ERACS but
figures taken directly from the generator test sheets and stator current decrement
curves have also been used. In order to calculate the fault current contribution
from a generator during an asymmetrical fault, the ERACS model has been used
in conjunction with information we have received directly from Leroy Somer. To
confirm these results, the multiplier factor between asymmetrical and symmetrical
faults has also been taken from other alternator stator current decrement curves to
provide an estimate of the asymmetric fault current.
5.1 Input data
The information in the following sections detail the data inputted into the ERACS
model in order to simulate the AMS06 network.
5.1.1 Liander Network Data
The following screenshots taken from the ERACS model indicate the Liander data
inputted to the model. As there are the two different network operating voltages
two separate input data files have been created to simulate the Liander network.

5.3 Transformer
The technical data sheet of the transformer, which is included as part of the
technical submittal, to be installed at AMS06 is included in the appendices. The
following images are screenshots taken from the ERACS model indicating the
data inputted to the model.
Note, that to accommodate the future upgrade of the Liander network from 10kV
to 20kV the transformers to be installed have two primary winding settings to
allow for the transformer primary voltage to be altered at the time of the upgrade.
Therefore two different input data files have been created for the transformers.
One for 10kV primary winding voltage, the other for the 20kV primary winding
voltage.
It should also be noted that the transformer technical data sheet and requirements
is for transformers with an 11% impedance. The transformer has been modelled in
accordance with IEC 60076-1 which states that the tolerance range of a
transformer this size is ±7.5% from the specified value. For the purpose of these
calculations, a 10.175% impedance has been modelled. This will give the worst
case anticipated fault levels.

Note that the impedance is determined by the following equation:
𝑍 = √𝑋2 + 𝑅2
Z is the impedance for one winding which is 10.175/2 = 5.0875%
R is the sequence resistance, taken from the data sheet as 0.3%.
Rearranging the formula to find the sequence reactance gives:
𝑋 = √𝑍2 − 𝑅2
𝑋 = √5.08752 − 0.32
𝑋 = 5.079%
Substituting these values back in to check Z gives:
𝑍 = √5.0792 + 0.32 = 5.089%
5.089 × 2 ≈ 10.175%
Note this formula applies to the input data used in sections 5.3.1.2 and 5.3.1.3
below.

5.3.2 Generator
The technical datasheets for the generators to be installed at AMS06 are included
in the appendices.
Following initial comments on revision 1 of this report regarding the generator
contribution to the maximum sustained short circuit, the first third of the first page
of the Leroy Somer test sheets for one of the alternators was provided. This was
included in the comments received.
The section of test sheet provided indicated that the short circuit multiplier was
4.73. This was inconsistent with the corresponding datasheet for the Leroy Somer
LSA 53.1 alternator.
Following subsequent discussions with Zwart the generator supplier and Emerson
/ Leroy Somer the alternator supplier with regards to the figures provided in the
test sheet it has been determined that this is the incorrect value upon which to base
the generator maximum short circuit current.
Arup have subsequently obtained the full test sheet from Emerson / Leroy Somer
on 24 April 2015. The following images show the FAT test reports for each of the
generator alternator.
It can be seen that the fault current is not calculated using the 4.73 or 4.29
multiplier as this is the value used without considering the AVR limitation.
Taking into account the AVRs that are to be used with these generators, the
sustained short circuit current is calculated using 3.1 or 3.17 multiplied by Irated.
The test sheets from Leroy Somer indicate that the maximum worst case sustained
short circuit current from one of the generators is 14.03kA.
This is detailed as shown on the two following test sheets.

5.3.3 MV Cabling
The technical datasheets for the MV cabling to be installed at AMS06 are
included in the appendices.
The table below show the cables that have been modelled in ERACS.
Cable reference Type Length
HV-CBL-KB/02 22kV 240mm2 Aluminium Single Core 45m
HV-CBL-C/001 22kV 150mm2 Aluminium Single Core 15m
The cables in the table above have been selected for the model as they represent
the shortest path from the Klantstation switchboard to the Power Block MV
switchboards. As these are the shortest cables, they which will have the lowest
impedance and therefore represent the highest fault current.
5.3.3.1 Ring MV Cable
The MV cable forming the ring for the facility from the customer MV switchgear
to the power block MV switchgear has an aluminium core in order to meet the
specification.
The following images is are screenshots taken from the ERACS model indicating
the data inputted to the model.

6 MV Switchboards
6.1 MV Switchboards
The Liander network maximum fault levels have been provided. As there are no
MV generators associated with the system the maximum fault level expected on
the MV switchboards is solely based upon the Liander network characteristics.
For the 10kV network the maximum fault level is 8.75kA
For the 20kV network the maximum fault level is 10.47kA
Therefore the maximum fault level is below the 20kA rating of the MV
switchboards.
The following screenshots taken from ERACS illustrate the calculated fault levels
for both network scenarios.

10kV Network
As can be seen in the images above, the fault current at the Klantstation
switchboards and the Power Block MV switchboards is 9.18kA and 9.09kA
respectively. As both of these switchboards are rated to 20kA, they are sufficient
for the maximum fault level on the 10kV supply.

Sustained Short Circuit Current
On the 20kV supply, the fault current at the Klantstation switchboard will be

Both of these switchboards are rated to 20kA and are therefore sufficiently rated
for the fault levels on the 20kV supply.

7 LV Switchboards
7.1 10kV Network Transformer Supply
The image below indicates that the maximum anticipated sustained short circuit
fault level on the LV switchboard when supplied by the 10kV Liander network.
This shows that the sustained fault current from 1 transformer is shown to be
26.3kA rms. This is below the short time withstand 50kA rms rating of the
switchgear so the switchboards are sufficiently rated for a single 10kV
transformer supply.

7.3 Generator Supply
This section details the results of calculations for when the generator is solely
supporting the site. The generator is modelled as 3.065MVA with the data as
detailed in section 5.3.2.
7.3.1 Symmetrical 3-Phase Sustained Fault
The model above show the sustained short circuit current as being 14.7 kA rms.
This sustained short-circuit current of 14.7kA rms is below the 50kA rms rating of
the switchboard and the sub-transient short circuit peak current is below the
105kA peak rating of the switchboard, therefore the switchboard is correctly rated
for the operation of a single generator.
Note that this is in fact a higher sustained short circuit current compared to the
Leroy Somer data of 14.03kA as it is not possible to model the AVR associated
with the generator.

7.4 Parallel 10kV Network Transformer Supply and
Generator
The operation of a transformer and generator in parallel was modelled under the
following conditions of the 10kV Liander network:
Symmetrical 3-Phase Sustained Fault
Symmetrical 3-Phase Sub-Transient Fault
Symmetrical Single Phase Sub-Transient Fault
Asymmetrical Single Phase Sub-Transient Fault
7.4.1 Symmetrical 3-Phase Sustained Fault
The sustained short-circuit current of 41kA rms is below the 50kA rating of the
switchboard and in practice the fault current will be less than this as the generator
fault current is limited by the AVR to 14kA.

7.4.3 Symmetrical Single Phase to Earth Sustained Fault
Current
The single phase to earth, sustained short circuit current is 54.9kA rms. This is
above the 1s sustained rating of the switchboard but this is an acceptable value
providing that the I2t value is maintained.
(50kA)2 x 1 = (54.9kA)2 x t
t = 0.83s
Providing the fault is disconnected in less than 0.83s then the sustained short
circuit current of 54.9kA rms is acceptable. The circuit breaker operation time will
be confirmed in the discrimination study.
7.4.4 Asymmetrical Single Phase to Earth Sub-Transient
Fault
For the asymmetrical fault calculation the making and breaking duties of the
circuit breakers have been analysed. The information below shows the making
and breaking times for the Siemens 1000A, 1250A and 4000A circuit breakers
that are being used.

7.4.4.1 Making Duty and Peak Switchboard Rating
The graph above shows a single phase to earth asymmetrical fault. The peak
current at 10ms is 129kA. In order to confirm the response of the generator, the
peak asymmetric fault current at 10ms was obtained in an email from Niek van
Hoecke of Leroy Somer (dated 06/05/15) which stated that the peak current from
the generator was 71.6kA peak.
The contribution from the transformer only is shown in the screenshot below.

6\TELECITY - AMS06 - FAULT LEVEL REPORT REV 6.DOCX
Page 37
The peak single phase to earth fault current at 10ms for the transformer is 63.5kA
peak. Adding this value of 63.5kA to the 71.6kA obtained from Leroy-Somer
gives a peak value of 135.1 kA.
Therefore the peak rating of the switchboard and the required making duty of
circuit breakers is at least 135.1kA. This means the peak rating of the switchboard
at 105kA and the 121kA circuit breaker making duty is inadequate.
Options to mitigate the impacts of these results it discussed in section 9.
7.4.4.2 Breaking Duty
The figure above shows that at 50ms, the breaking duty required is 55.9kA rms.
A figure for the rms asymmetric current from the generator at 50ms could not be
obtained from Leroy-Somer so the above value could not be directly cross
checked. Using other stator decrement curves, it can be seen that by 50ms the DC
offset has decayed to near 0. This means that the single phase asymmetrical fault
should be similar to the single phase symmetrical fault current.

At 50ms the symmetrical current is 6.3 x 4424 = 27.8kA rms.
The rms contribution of the transformer at 50ms during an asymmetrical fault is
given below.
Summing the rms asymmetrical fault current from the transformer of 29.7kA with
the 27.8kA calculated for the generator gives a required break capacity of 57.5kA
rms.
As this figure is higher, a minimum breaking capacity of the circuit breakers of
57.5kA rms is recommended for the 10kV supply.

7.5.4 Asymmetrical Single Phase to Earth Sub-Transient
Fault
For the asymmetrical fault calculation a single phase to earth fault has been
simulated to calculate the required making and breaking duties of the circuit
breakers and the peak rating of the switchboard. Refer to section 6.4.3 for the
information relating to the making and breaking times for the Siemens 1000A,
1250A and 4000A circuit breakers.
7.5.4.1 Making Duty and Peak Switchboard Rating
The graph above shows a single phase to earth asymmetrical fault. The peak
current at 10ms is 133kA. In order to confirm these results the peak asymmetric
fault current from the generator at 10ms of 71.6kA (as discussed in section
7.4.4.1) can be used.

The contribution from the transformer only at 20kV is shown in the screenshot
below.
The peak single phase to earth fault current at 10ms for the transformer is 66.7kA
peak. Adding this value of 66.7kA to the 71.6kA obtained from Leroy-Somer
gives a peak value of 138.3kA.
Therefore the peak rating of the switchboard and the required making duty of
circuit breakers is at least 140kA. This means the peak rating of the switchboard
at 105kA and the 121kA circuit breaker making duty is inadequate.
Options to mitigate the impacts of these results are discussed in section 9.

7.5.4.2 Breaking Duty
The figure above shows that at 50ms, the breaking duty required is 57.8kA rms.
As figure for the rms asymmetric current from the generator at 50ms could not be
obtained from Leroy-Somer in order to cross check the above value, a figure of
27.8kA rms can be taken from the symmetrical fault stator current decrement
curves. See section 7.4.4.2 for further information on this.
The rms contribution of the transformer at 50ms during an asymmetrical fault on
the 20kV supply is given below.
Summing the rms asymmetrical fault current from the transformer of 31.4kA with
the 27.8kA calculated for the generator gives a required break capacity of 59.2kA.
As this figure is higher, a minimum breaking capacity of the circuit breakers of
60kA is recommended.

9 Conclusion
This report has demonstrated that the switchboard and circuit breakers are
adequately rated for operating on either a single transformer or a single generator.
However, in the scenario where the transformer and generator are operated in
parallel the switchboard and circuit breakers are not rated adequately with regards
to the peak fault level. Paralleling the sources also exceeds the maximum making
duties of the 1000A and 1250A circuit breakers.
As part of this fault level study data has been provided by the generator and
alternator supplier Leroy Somer with regards to the peak asymmetric fault level.
They were however unable to provide the asymmetric decrement curve for the
alternator as this information is no longer standard issue and as such cannot be
obtained. Therefore the worst case figures of 71kA has been used as the
asymmetric fault peak anticipated.
It is therefore recommended that the operation mode where the transformer /
mains supply runs in parallel with the generator is excluded. During this parallel
operating mode the peak fault levels may exceed the switchboard and circuit
breaker ratings. During this operating mode the peak fault levels may exceed the
switchboard rating. This solution will match the recommendations for AMS05
and the current operating procedure for that existing facility.
It is therefore recommended that interlocks are provided on the switchboard
between the transformer, generator and switchboard buscoupler is provided to
ensure that only 2 out of 3 circuit breakers are closed at any one time to prevent
paralleling between the transformer and generator.

ERACS - Electrical Power Systems Analysis SoftwareCobham Technical Services ERA Technology
The most important thing we build is trust
ERACS - Electrical Power Systems Analysis SoftwareInnovation in Power Systems Analysis Software Technology
The economic design of power systems is
critically dependent on being able to predict
the system behaviour under both normal
and abnormal operating conditions. Hand
calculations and estimates are possible but
increasingly expensive in engineers’ time and
run the risk of introducing errors resulting in
significant safety and reliability implications.
ERACS is Cobham Technical Services’ suite
of power systems analysis software. It allows
users to simulate electrical power system
networks quickly and easily to judge their
correct, safe and timely operation.
ERACS software is at the forefront of
development taking account of both the
continuing pressure for ever easier operational
software and the increasing technical needs
of modern engineering.
The name ERACS is synonymous with quality,
reliability, accuracy, ease of operation and
adaptability to changing market needs.
Benefits
Using ERACS to conduct power system
analysis, clients are able to:
save costs
reduce risk
improve system quality
increase reliability and safety.
System
ERACS software is PC-based, fully integrated
and has an easy to use interface. The data
is entered once only in a central database,
making data management a very simple
procedure. Networks for simulation by ERACS
may be either radial or fully interconnected
systems or a mixture of both (HV to LV).

Ltd’s ISO 9001 and TickIT certified quality
system.
Why ERACS?
The ERACS suite of power systems analysis
software is in constant use by experienced
Cobham power engineers for system study
purposes. They have direct input into the
program development to incorporate best
practices currently in use within the electrical
industry. ERACS’ diverse user base (including
offshore, marine, mining, utilities, transport
and academia) is encouraged to contribute
to the development and direction of the
programs. In this way the ERACS programs
are constantly moving forward, providing real
benefits in terms of reduced study times and
improved technical capability to users, and
meeting the specific needs of engineers with
practical problems to solve.
The provision of a dedicated ERACS user
website and support hotline further benefits
its user base. Staffed by electrical/software
engineers with a great depth of understanding
of the latest programming techniques and
tools, they also have direct access to Cobham’s
own leading power systems engineers for
Protection Co-ordination

technical support. The ERACS support team
prides itself on its fast response time to
technical queries from its software users.
The ERACS Loadflow program models
radial and mesh/interconnected AC three
phase LV to HV systems with multiple
generation sources. Loadflow calculates:
system losses, power/VAr/current flows
(on screen arrows indicate direction),
transformer tap settings, equipment
loading and voltage profiles (plus many
more). As with all ERACS programs,
results can be selected and displayed on
the single line diagram or saved to printed
output and may be exported to other
applications for the generation of user
customised reports.
The ERACS Fault programs (Classical &
IEC909) allow all classical fault types to
be applied to system elements with an
additional survey option to automate
this process.
The ERACS Harmonic Injection program
allows multiple harmonic sources to be
connected to the system and their effect
calculated. Results include total harmonic
voltage and current distortion and their
individual harmonic components in both
graphical and numerical formats.
The ERACS Harmonic Impedance program
calculates the harmonic impedance
profiles between selected system busbars,
indicating possible system resonance.
The ERACS Harmonic G5/4 program allows
the connection of non-linear equipment
to be assessed against the planning levels
specified in ER G5/4.
The ERACS Protection Co-ordination
program is four programs in one and
includes:
Protection Device Setting: Relays, fuses
and circuit breakers are added from the
ERACS data library to the single line diagram.
Settings and discrimination times are then
graphically selected.
Protection Stability Checking: Having selected
the desired settings the protection program
checks that no devices operate under steady
state loadflow conditions or as a result of
network reconfiguration.
Protection Dynamic studies: Any one of the
classical fault conditions can be applied to
any part of the network to evaluate the
dynamic operation of the protection scheme.
ERACS steps through stage by stage to
confirm (or not) that the location of the
fault can be isolated in an acceptable manner.
Protection Analyser: This single operation
allows every element in the network to be
faulted individually and the corresponding
protection scheme reactions logged. User
friendly graphical reporting allows weaknesses
and failures in the total protection scheme to
be quickly identified. All backed up by a large
library of equipment and manufacture’s data
The ERACS Arc Flash Hazard Assessment
program examines the electrical network
to determine the severity of arc flash
hazards and recommends appropriate
PPE to IEEE 1584 and NFPA 70E. Warning
labels can also be generated (and
customised) from the tabulated results.
The ERACS Transient Stability program
allows dynamic system behaviour to
be studied (e.g. motor starting, fault
application, load application, load rejection
and generator behaviour). A timeline of
multiple events is selected with the result
shown graphically and on the single
line diagram.
The ERACS Universal Dynamic Modeller
(UDM) allows AVR, Governor and controlled
shunt models (DFIG’s, PFC’s , SVC’s, saturable
reactors etc) to be built and configured
for use within Loadflow or Transient
Stability studies.
Cobham Technical Services also supply
GroundRod substation earthing software,
standalone Arc Flash Hazard calculator and
