Voltage detection system (VDS) and protection element for medium voltage switchgear with relay contacts  



Main functions

  • Test for voltage absence in medium voltage systems according to VDE 0682-T415 or IEC 61243-5. Voltage test system according to protection relay standard IEC 60255 and VDS standard IEC 61243-5. The CAPDIS S2_55 is specially dimensioned for use in power plants as well as for protective purposes. It is dimensioned in such a way that it can permanently withstand even high-frequency disturbances from atmospheric surge voltage loads, reignitions and resonance vibrations at all inputs and outputs and can additionally absorb them up to an innocuous degree from the capacitive divider. This also prevents the spread of interference radiation to the rest of the secondary operating devices. With this extended immunity, the CAPDIS S2_55 can be used not only for pure stress testing but also for safety-relevant functions.

  • Swichting error protection: The propagation of decentralized feeds requires the installation of a rear voltage detection with switching fault protection in substations and protection stations. Instead of output voltage converters, CAPDIS-S2_55  capacitive voltage test systems are used, which can also be functionally matched to the field control and protection device. The rear voltage detection serves on the one hand for personal safety and on the other hand for switching error protection by locking the grounding switch with the pending rear voltage.
  • Island network warning: In substations, the island network warning must also be checked when the circuit breaker is switched off to check whether the rear voltage is pending. If this is the case, an island network warning is generated in the field guide and protection device, which prevents autmatic connection during an AWE (automatic reconnection) when the rear voltage is pending.
