Ready-for-service indicator
Characteristics
Self-monitoring; easy to read
Independent of temperatureand pressure variations
Independent of site altitude
Only responds to changes ingas density
Option: Alarm switch1 NO contact for remoteelectrical indication
Mode of operation
For the ready-for-service indica-tor, a gas-tight measurementbox is installed on the inside ofthe switchgear vessel.
A coupling magnet, which isfitted to the bottom end of themeasurement box, transmitsits position to an outside arma-ture through the stainless steelswitchgear vessel. This arma-ture moves the ready-for-ser-vice indicator of the switchgear.
While changes in the gasdensity during the loss of gas,which are decisive for theinsulating capacity, are dis-played, temperature-depen-dent changes in the gaspressure are not. The gas inthe measurement box has thesame temperature as that inthe switchgear.
The temperature effect iscompensated via the samepressure change in both gasvolumes.
Verification of correctterminal-phase connections
Possible by means of aphase comparison test unit(can be ordered separately)
Safe-to-touch handling of thephase comparison test unit byinserting it into the capacitivetaps (socket pairs) of theswitchgear or the feeders.

Interlocking systems and locking devices
Interlocking of connectioncompartment
Ring-main andcircuit-breaker panel
Access to the cable con-nection compartment(e.g. for cable testing) isonly possible providedthat the feeder is isolatedand earthed (three-posi-tion switch-disconnectorin EARTHED position)
Option: Closing lock-outThis prevents the three-position switch-discon-nector from beingswitched from OPEN toCLOSED position,when the cable compart-ment cover is removed
Transformer panel
Access to the cable con-nection compartment andto the HV HRC fuse com-partment (e.g. for replace-ment of HV HRC fuselinks) is only possible pro-vided that the feeder isisolated and earthed(three-position switch-disconnector inEARTHED position)
Option: De-earthinglock-outThis prevents thethree-position switch-disconnector from beingswitched from positionEARTHED to OPEN.
Switchgear interlocking
Dependent on the va-cuum circuit-breaker oper-ating mechanism with
Spring-operated or Stored-energy mechanism
Option: Switchgear-sidemechanical interlockingwith three-positionswitch-disconnector
Vacuum circuit-breakercannot be closed whenthree-position switch-disconnector is in theOPEN position:
Spring-operated mecha-nism: Hand crank openingis blocked
Stored-energy mechanismwith closing solenoid3AY15 10: Pushbutton(S12) operated by mecha-nical interlock preventscontinuous command toclosing solenoid

Type of service location
SIMOSEC switchgear can beused as an indoor installation inaccordance with IEC 61936(Power installations exceeding1 kV AC) and VDE 0101
Outside lockable electricalservice locations at placeswhich are not accessible tothe public. Enclosures ofswitchgear can only beremoved with tools.
Inside lockable electricalservice locations. A lockableelectrical service location isa place outdoors or indoorsthat is reserved exclusively forhousing electrical equipmentand which is kept under lockand key. Access is restrictedto authorized personnel andpersons who have beenproperly instructed in electri-cal engineering.Untrained or unskilled per-sons may only enter underthe supervision of authorizedpersonnel or properly instruc-ted persons.
Terms
Make-proof earthing switchesare earthing switches withshort-circuit making capacityaccording to IEC 62271-102
and VDE 0671-102
Colour of panel front
Siemens standard (SN)47 030 G1,colour no. 700 / light basic(similar to RAL 7047 / grey)
Insulating capacity
The insulating capacity is veri-fied by testing the switchgearwith rated values of short-duration power-frequencywithstand voltage and light-ning impulse withstand volt-age according to IEC 62271-1/VDE 0671-1 (see tableInsulating capacity).
The rated values are referredto sea level and to normalatmospheric conditions(1013 hPa, 20 C, 11 g/m3humidity in accordance withIEC 60071 and VDE 0111).
The insulating capacitydecreases with increasingaltitude.For site altitudes above1000 m (above sea level)the standards do not provideany guidelines for the insula-tion rating. Instead, specialregulations apply to thesealtitudes.
Site altitude As the altitude increases, the
insulating capacity of insula-tion in air decreases due tothe decreasing air density.This reduction is permitted upto a site altitude of 1000 maccording to IEC and VDE.
For site altitudes above1000 m a higher insulationlevel must be selected. Itresults from the multiplica-tion of the rated insulationlevel for 0 to 1000 m with thealtitude correction factor Ka.
Result:
According to the abovetable, a switchgear for arated voltage of 24 kV witha rated lightning impulsewithstand voltage of125 kV is to be selected.

Standards, specifications, guidelines, classification
Internal arc classification(option)
Safety of operating personnelensured by tests to verify in-ternal arc classification
The possibility of arc faultsin SIMOSEC switchgear ismuch less due to:
Metal-enclosed and gas-insulated switching functions(e.g. of three-position switch-disconnector and 3AH5vacuum circuit-breaker)
Logical arrangement ofoperating mechanismelements and mechanicalinterlocks
Short-circuit-proof feederearthing by means of thethree-position switch-disconnector
The internal arc fault testsmust be performed in accord-ance with IEC 62271-200/VDE 0671-200 *
Criteria for internal arc faults
Criteria according toIEC 62271-200/VDE 0671-200 * with respectto the behaviour in case ofinternal arc faults
Definitions of criteria: Acceptance criterion 1
Covers and doors remainclosed. Limited deformationsare accepted.
Acceptance criterion 2No fragmentation of theenclosure. No projection ofsmall parts above 60 gweight.
Acceptance criterion 3No holes in the accessiblesides up to a height of 2 m.
Acceptance criterion 4Indicators do not ignite dueto the effect of hot gases.
Acceptance criterion 5The enclosure remainsconnected to its earthingparts.

before the test:
Remove or disconnect anyvoltage transformers at thecable connection inSIMOSEC switchgear.
SIMOSEC switchgear forrated voltages up to 24 kVcan be subjected to cabletests at a max. DC testvoltage of 72 kV or accordingto VDE at 70 kV, 15 min.The voltage at the busbarmay be 24 kV in this case.

Climate and ambientconditions
SIMOSEC switchgear may beused, subject to possible addi-tional measures e.g. panelheaters or floor covers under the following ambientconditions and climate classes:
Ambient conditions Natural foreign materials Chemically active pollutants Small animals
Climate classesThe climate classes areclassified according toIEC 60721-3-3
SIMOSEC switchgear is largelyinsensitive to climate andambient conditions by virtue ofthe following features:
No cross insulation forisolating distances betweenphases
Metal enclosure of switchingdevices (e.g. three-positionswitch) in gas-filled stainless-steel switchgear vessel
Dry-type bearings inoperating mechanism
Essential parts of the operat-ing mechanism made ofcorrosion-proof materials
Use of climate-independentthree-phase current trans-formers
