  • Page 3: General Description

    660 Volts is the maximum system operating voltage for the D64RP14 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 D64RP14 can be applied on any system voltage.

    PUB 51079 D64RP14 SERIES A2 DIGITAL GROUND FAULT RELAY OPERATION GLOSSARY OF TERMS Manual Reset: A N.O. contact remote RESET pushbutton connected to terminals R1 and R2 of the D64RP14 must be pressed once to reset the output relay after a trip, providing the ground fault has been cleared or the measured values are within the preset limits.
  • Page 5 The system primary phase current on which the D64RP14 is being applied exceeds 100 Amps continuous. Any Eaton’s Cutler-Hammer C311CT with 500:1 ratio may be used when the above requirements dictate the use of an external CT. The ground fault trip current setting range of 1 Amp –...

    PUB 51079 D64RP14 SERIES A2 DIGITAL GROUND FAULT RELAY The two secondary terminals of the external CT are to be connected to terminals T1 and T2 of the D64RP14. Chassis Ground Chassis ground is the ground to which all of the non-current carrying metal equipment is connected/bonded.
  • Page 7: Ground Fault Trip Delay Time

    PUB 51079 D64RP14 SERIES A2 DIGITAL GROUND FAULT RELAY As indicated in the General Description, it is recommended that the ground fault TRIP LEVEL setting be kept as close to the charging current as possible. This will provide maximum safety for operating personnel and equipment protection.

    PUB 51079 D64RP14 SERIES A2 DIGITAL GROUND FAULT RELAY The D64RP14 will work with Eaton’s Cutler-Hammer C311CT current transformers having a turns ratio of 500:1. These are epoxy molded to give exceptional mechanical properties and have high-grade silicon iron cores for excellent coupling characteristics.
