LED voltage indicators for reliable status monitoring of medium-voltage systems

The SPA voltage indicator is used for permanent display of the voltage status in medium-voltage networks from 5 kV to 36 kV. When voltage is applied, one LED per conductor flashes continuously, clearly indicating the operating status. The system is available in two versions: with a potential-free fiber optic connection between the sensor and the display unit (SPA-L) or as a directly connected version for insulators and bushings (SPA-S). It is operated via an external power supply. In addition, up to three freely definable remote signaling contacts are available.

  • Operating range from 5 kV to 36 kV
  • Permanent LED display per conductor
  • SPA-L version with fiber optic connection
  • SPA-S version for direct mounting
  • Up to three configurable remote signaling contacts
