  • Page 3: General Description

    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.
  • Page 4 PUB 50411 D64RP18 SERIES B1 DIGITAL GROUND FAULT RELAY Pulsed (Trip) Auto Reset: Each time control power is applied, the internal processor of the D64RP18 selects this mode when it sees a closed circuit on terminals R1 & R2 (there is a jumper or a N.C. pushbutton connected to R1 and R2).

  • Page 5: Dipswitch Settings

    The system primary phase current on which the D64RP18 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 30 mA –...

  • Page 7: Output Relay Contact State

    PUB 50411 D64RP18 SERIES B1 DIGITAL GROUND FAULT RELAY OUTPUT RELAY CONTACT STATE The output relay contact state is determined by the operating mode selected and the sensing condition of the D64RP18 relay. This is shown in Table 2. Use this table when deciding on field connections. Refer to the CONNECTIONS section.

  • Page 8: Built-In Current Transformer

    Refer to the Glossary of Terms to determine if an external Current Transformer is required for the application. The D64RP18 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.

    PUB 50411 D64RP18 SERIES B1 DIGITAL GROUND FAULT RELAY The terminals are pull apart. If an external CT is being used, connect the two secondary terminals of the CT to terminals T1 and T2 of the relay using 14 AWG (minimum). Twist the leads to optimise electromagnetic immunity. Note: The CT’s input terminals T1 and T2 are NOT isolated from the control voltage.
