(230V and 400V)

urban type in bricks rural type installed externally directly on the MV pylon

private substations belong to the user civil users (schools, hospitals, etc.) and industrial users are mostly located in the same rooms of the factory

General Information MV/LV Transformer Substations

Typical structure of a substation where the switching apparatus of

the utility is installed.

where the measuring units

are located

contains the transformer and

the MV and LV switching

apparatus


Most common management methods

Substation with a single transformer



Substation with two transformers

(one as a spare for the other)

It is possible to use the

Emax with a wire interlock

(mechanical interlock)

between two CBs



two transformers which operate

in parallel on the same busbar


two transformers which operate simultaneously on

two separate half-busbars



It is possible to use the

Emax with a wire interlock

(mechanical interlock)

between three CBs

MV/LV transformers is the most important part of the transformer substation single transformer for low powers (up to 630kVA - 800kVA) several units in parallel for higher powers (1000kVA - 2500kVA) type of cooling system

Low voltage selectivity with ABB circuit breakers Selectivity definitions and Standards

Definitions and Standards

Selectivity techniques


Back-up protection

Agenda Low voltage selectivity with ABB circuit breakers

Selectivity (or discrimination)

is a type of coordination of two or

more protective devices in series.

Selectivity is done between

one circuit breaker on the supply side

and one circuit breaker, or more than

one, on the load side.

A is the supply side circuit

breaker (or upstream)

B and C are the load side circuit

breakers (or downstream)

Introduction What is selectivity?

Better selectivity

FAULT CONTINUITY OF SERVICE DAMAGE REDUCTION

Fast fault elimination

Reduce the stress and prevent damage

Minimize the area and the duration of power loss

Introduction Protection system philosophy

Selective coordination among devices

is fundamental for economical and technical reasons

It is studied in order to:

rapidly identify the area involved in the problem;

bound the effects of a fault by excluding just the affected zone of the network;

preserve the continuity of service and good power quality to the sound parts of the network;

provide a quick and precise identification of the fault to the personnel in charge of maintenance or to management system, in order to restore the service as rapidly as possible;

achieve a valid compromise between reliability, simplicity and cost effectiveness.

Main purposes of coordination Selectivity purpose

The definition of selectivity

Trip selectivity (for overcurrent) is a coordination between the operating characteristics of two or more overcurrent protection

devices, so that, when an overcurrent within established limits

occurs, the device destined to operate within those limits trips

whereas the others do not trip

IEC 60947-1 Standard: Low voltage equipment

Part 1: General rules for low voltage equipment

Standards definition Selectivity

IEC 60947-1

def. 2.5.23

In occurrence of a fault

(an overload or a short circuit)

if selectivity is provided

only the downstream circuit

breaker opens.

Overcurrent selectivity Example

All the system is out of service!

In occurrence of a fault

(an overload or a short circuit)

if selectivity is not provided

both the upstream and the

downstream circuit breakers

could open

Overcurrent selectivity Example

A and B connected in series:

partial selectivity and total selectivity.

Standards definition Partial and total selectivity

IEC 60947-2

def. 2.17.2 - 2.17.3

Partial selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series,

the load side protection device carries out the protection up to a

given level of overcurrent, without making the other device trip.

B opens only according to fault current

lower than a certain current value;

values equal or greater than Is

will give the trip of both A and B.

Is is the ultimate

selectivity

value!

Is = ImA

Standards definition Partial selectivity

Only B trips for every current value

lower or equal to the maximum

short-circuit current.

Total selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series,

the load side protection device carries out the protection without

making the other device trip.

Here the selectivity is a total selectivity,

because it is guaranteed up to the maximum

Circuit breaker A will be set to a value which does not

trip for faults which occur on the load side of B.

occur on its load side (I3Bmax < 1kA)

Back-up protection Back-up protection


Back-up protection (or cascading)

is a type of coordination of two protective

devices in series which is done in electrical

installations where continuous operation is

not an essential requirement.

Back-up protection What is back-up protection?

Back-up protection

excludes the use

of selectivity!!!

The definition of back-up is given by the

Back-up is a coordination of two overcurrent protective devices in series, where the protective device on the supply

side, with or without the assistance of the other protective

device, trips first in order to prevents any excessive stress on

downstream devices.

IEC 60947-1 Standard: Low voltage equipment

Part 1: General rules for low voltage equipment

Back-up protection Standards definition

IEC 60947-1

def. 2.5.24

Back-up is used by those who need

to contain the plant costs

The use of a current-limiting circuit

breaker on the supply side

permits the installation of lower performance

circuit breakers on the load side

Both the continuity of service and the selectivity are sacrificed

How it works DOC How it Works

Features - Professional and Light Profiles

DOC can be used with 2 different profiles

Depending on the user needs and skills it can be recommended to use

the Light Profile which hides the advanced and complex features

DOC Light is for ...

... first time, unskilled DOC users

... installers panel builders

who need a simple tool to draw

and verify small networks

DOC Professional is for ...

... skilled DOC users

... customers working on industrial

applications

... engineering companies

OEMs looking for a powerful

calculation and design tool

Features - MV Diagram Drawing

The Medium Voltage section of the project can be drawn by the Macros

of the typical units of the Unimix switchboard or by Objects for more

flexibility

To pass to the Low Voltage section it is necessary to use the

transformers (when a low voltage section is not needed, the drawing

can be completed with MV Loads or Motors)
