The D64RP18 is a microprocessor based ground fault relay for use on solidly grounded or resistance grounded systems. This innovative digital electronic relay measures ground fault current using a built-in 1.1” zero sequence current transformer (CT). The D64RP18 reacts to alternating current only and will reject direct current signals. It will maintain accuracy over a frequency range of 45 to 450Hz, making it suitable for variable frequency drive applications. 660 Volts is the maximum system operating voltage for the D64RP18 when passing the system power conductors through the built-in CT. However, by using any Eaton’s Cutler-Hammer C311CT zero sequence current transformers with 500:1 ratio, connecting the secondary to terminals T1 and T2 of the relay, and passing the system insulated power conductors through the window of this CT, the D64RP18 can be applied on any system voltage. The ground fault current trip level is set on a front accessible binary DIPswitch array. Trip currents from 30 milliamps - 6 Amps can be selected in 8 discrete steps. These same trip settings are available when using any C311CT 500:1 ratio external CT. The trip level can be set just above the charging current 1 . Any deterioration in the circuit will trip the relay. This also permits scheduled field testing of the relay (by lowering the trip level).
