Product information "CAPDIS-S2_55 (R5)"

Voltage detection system (VDS) for medium voltage switchgear with relay contacts  and partial discharge (PD) monitoring


Main functions

  • Test for voltage absence in medium voltage systems according to VDE 0682-T415 or IEC 61243-5

  • Detection of partial discharge (PD)
  • Maintenance-free due to permanent self-monitoring

  • Relay contacts for safe remote monitoring of voltage levels and device status

  • Intrinsically safe - no additional test equipment required

Additional functionality

  • Integrated three-phase continuous display

  • No battery or additional auxiliary voltage required for voltage test and self-test

  • Complete insulation monitoring of the capacitive divider

  • Simple adjustment of the capacitive voltage divider with capacitor C2m module

  • Simple self-test without battery or additional auxiliary voltage

  • Integrated three-phase measuring point for phase comparison, rotating field direction measurement, etc.

  • Interface for smart grid systems for voltage measurement and fault monitoring

  • Active integrated conductor break detection


Clear distinction from

  • Overvoltage

  • Operating voltage

  • Voltage below operating voltage

  • Voltage absence

  • Fault

  • Indication of detected partial discharge

Relay outputs and LED indicators

  • Two integrated signal relays (changers) for remote monitoring of voltage states

  • Additional status display of the relays via LEDs on the front side

  • Auxiliary voltage required for relay functions

Simple adjustment of the capacitive voltage divider

  • adjustable 6-stage capacitor C2m module

Gas-insulated medium-voltage switchgear

Retrofitting in air-insulated medium voltage switchgear

Use of the CAPDIS-S1 also in air-insulated medium voltage switchgears

Integrated voltage systems are almost always used in gas-insulated switchgears (new systems).

Increasingly, customers are also using the CAPDIS-S1 in air-insulated switchgears for retrofitting. This brings these customers significant advantages:

  • Voltage-free testing can be carried out when the system is closed.
  • This significantly improves both the personal and the plant safety.
  • The operator is thus protected from interference arcs .
