Surge voltage generators are used for pre-location and pinpointing of high- and low-resistive as well as intermittent faults in power cables. The energy stored in a high-voltage capacitor is released at regular intervals or as DC voltage. The thus generated acoustic signal at the fault position can be recorded with a ground microphone and a universal receiver

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
