Differential Current Monitoring

The differential current or fault current monitoring is used in grounded systems to protect people and devices.

The protection of people and devices are done through a residual current circuit breaker.  These have the disadvantage that all connected system components are disconnected in the case of a fault.  The system then comes to a halt and can cause production losses.

For preventive maintenance differential current relays are used.  These display the current fault current through signal relays and monitor the possible current loops from the deterioration.

The information gathered here reduces the occurance of interruptions, failures, and fires.
