Retrofit Voltage detection system (VDS) for medium voltage switchgears - for retrofitting old HR interfaces



Main functions

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

  • Retrofit of old capacitive HR interfaces
  • 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

  • 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

Voltage level indication

Clear distinction from

  • Overvoltage

  • Nominal operating voltage

  • Voltage below operating voltage

  • Voltage absence

  • Fault

Fast and cost-effective solution for defective HR interfaces

1. Initial situation

HR interface: repeat check required every 6 years; low life expectancy due to high insulation requirements.

2. Mounting CAPDIS-PI

3. Possibly adjust capacity

If the HR interface is defective, i.e. not all 3 full flash arrows appear with a standard CAPDIS-PI at the pending nominal voltage, an adjustable CAPDIS-PI RR4 is set up. The defective phases are reconfigured via DIP switches until three full flash arrows are displayed. No external measuring device is required for parameterization.

4. Result

  • Repeat test-free voltage test system according to VDE 0682 T 415
  • Testing for voltage-free without additional equipment
  • Simplified earth fault detection at a glance
  • Integrated self-test function

 


Bericht eines Anlagenbetreibers nach der Umrüstung auf CAPDIS-PI:

Defekte kapazitive HR-Schnittstellen, die bereits einen Isolationsverlust des kapazitiven Teilers angezeigt hatten, konnten durch Installation des speziellen Retrofit-Geräts Capdis-PI-RR3 in etwa zehn Minuten wieder komplett ertüchtigt werden, ohne dass die Anlage abgeschaltet oder zerlegt werden musste.

Durch die Komplettsanierung der hochohmigen, kapazitiven Schnittstellen mit den Capdis-PI-Spannungsprüfsystemen von Kries-Energietechnik haben die wir die Lebensdauer der kapazitiven Teiler erheblich verlängert, ohne die Lebensdauer der Schaltanlage zu vermindern.
