Product information "CAPDIS-S1+ (R4.5)"

Voltage detection system (VDS) for medium voltage switchgears 

Main functions

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

  • Maintenance-free due to permanent self-monitoring

  • Intrinsically safe - no additional test equipment required

Additional functionality

  • No battery or additional auxiliary voltage required

  • Complete insulation monitoring of the capacitive divider

  • Active integrated conductor break detection

  • Simple adjustment of the capacitive voltage divider with C2m capacitor 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

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 absence 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 light arcs .
