Product information "CAPDIS-S2_55 (R4.5)"
The CAPDIS-S2_55 R4.5 is an integrated Voltage Detecting Systems for checking for absence of voltage in medium-voltage switchgear according to IEC 62271-213:2021 (or IEC 61243-5) with integrated three-phase continuous indication and Signaling outputs.

Voltage Detecting Systems VDIS for Medium Voltage (1..52 kV)

Testing for absence of voltage in medium voltage switchgear according to IEC 61243-5 or IEC 62271-213 with integrated three-phase continuous indication.

Application in power switchgear and for protection purposes

as an active element of the protection chain

Fail-safe Voltage Testing and Protection

Voltage Detecting Systems according to protection device standard IEC 60255 and Voltage Detecting Systems standard  IEC 61243-5 or IEC 62271-213. The CAPDIS-S2_55 is specially dimensioned for use in power systems as well as for protection purposes and absorbs high-frequency disturbances from atmospheric surge voltage loads, backfiring and resonance oscillations at all inputs and outputs. This also prevents the propagation of interference to the rest of the secondary equipment. The extended immunity to interference allows the CAPDIS-S2_55 to also be used for safety-relevant functions.

Switching fault protection

The spread of decentralized feeders requires the installation of reverse voltage detection with switching fault protection in substations and protection stations. The reverse voltage detection is used for personal safety and switching fault protection by interlocking the earthing switch in the event of reverse voltage.

Island network warning

In substations, for the island network warning, it must also be checked whether reverse voltage is present when the circuit breaker is open. If this is given, an islanding warning is generated from this in the field control and protection device, which prevents automatic connection during an AWE (automatic reclosure) when reverse voltage is present.

Protection device standard IEC 60255

meets the IEC 60255 standard and is thus authorized for protection and safety functions.

Integrated interface to voltage monitoring module CAPDIS-M

Maintenance-free, complete self-monitoring

the 3-stage voltage display exempts the CAPDIS® from repetition testing according to  IEC 61243-5 or IEC 62271-213 and BGV A3. The device does not require a battery even for the self-test according patent DE 103 04 396.

Relay outputs for protection function and LED indicators

Two power relays (changeover contacts) are operated with universal auxiliary voltage.Status indication by means of LEDs in the front.
