Ground Fault
In isolated or high impedance-grounded systems, core-balanced current sensors
are typically used to detect low level ground faults caused by insulation
breakdowns or entry of foreign objects. Detection of such ground faults can be
used to interrupt the system to prevent further damage, or to alert the
appropriate personnel to perform timely maintenance.
The SMC-50 module can provide ground fault indication when used with the
150-SM2 Option Module and an external core balance current transformer.
