Open the catalog to page 2Preventative maintenance Protection Data collection Continuous monitoring of residual current has proved to be an effective method of maintaining preventative maintenance systems. The result of monitoring the electrical network is a more reliable and “cleaner” electrical system. Continuously monitoring units detects faults and generates alarms for the following: • insulation damage or degradation • wiring errors • neutral-to-ground faults • connection of defective devices • leakage currents insufficient to blow a fuse or to trip a circuit breaker. Residual current is measured by a sensitive...
