Voltage detecting systems

Wega 1.2 C

Integrated voltage detecting system with display

Wega 1.2 C is a 3-phase voltage detecting system, which indicates the following operating voltage states:

The built-in display test function at the front enables verification of the display of the installed and de-energised unit.

For connection, either shielded or unshielded cables with flat connectors or system connectors can be used.

  • Designed according to IEC 61243-5 (VDE 0682-415)
  • Wide-range Wega (e.g. 10 – 20 / 24 kV): Reduction of variants
  • Integrated maintenance test: maintenance-free
  • Retrofit ready: connection to ComPass B and Sigma D series
  • Front accessible LRM interface: fully featured according to IEC 61243-5
  • Fully enclosed electronics: high functional reliability
  • Overvoltage indication: phase-selective
