Power supply circuits continuity check relay type KO-3
Application
- monitoring the supply circuits of the cable boxes and instrumentation boxes heaters
- monitoring the current flow in three supply circuits:
- one three-phase circuit,
- three circuits supplied by one phase,
- three independent circuits,
- current control in the local switch redundancy automatics
Advantages
- Digital algorithms for the current measurement (LEM converter)
- DC or AC measurement
