Application
The relay type ND10 provides sensitive, high operating
speed and selective restricted differential protection
against ground faults of power transformer or
generators. Both biased or high impedance types are
available.

50N/51N - 87NHIZ Residual overcurrent or high
impedance restricted differential ground fault
50N/51N Calculated residual overcurrent
64REF Biased restricted differential ground
fault
