WARNING!

To avoid personal injury or equipment damage, only qualified personnel should perform the procedures in this manual.

NOTE

Be sure that the relay is hard-wired to earth ground with no smaller than 12 AWG copper wire attached to the ground terminal on the rear of the unit case. When the relay is configured in a system with other devices, it is recommended to use a separate lead to the ground bus from each unit.

BE1-64F Introduction

SECTION 1 • GENERAL INFORMATION

INTRODUCTION

The BE1-64F Ground Fault Relay detects and annunciates ground faults in the normally ungrounded field circuit of a synchronous machine. A short-circuit in a synchronous machine’s field can often be prevented by detecting and removing a ground fault before a second ground fault results in serious damage.

BE1-64F relays are compatible with continuous field voltages up to 600 Vdc and forcing voltages up to 750 Vdc for one minute. During reverse excitation (negative forcing), BE1-64F relays will withstand up to 1,200 Vdc for one minute.

NOTE

To ensure protection against field grounds, the rotor iron must be grounded. Do not rely on a ground path through the rotor bearings. Grounding must not be installed where it bypasses the bearing insulation that prevents shaft currents. Rotor grounding recommendations for a machine should be obtained from the machine manufacturer.

Two sets of relay outputs and front panel indicators are provided for fault annunciation and tripping duty. One set of output contacts, one front panel indicator, and a latching target indicator annunciate the detection of a ground fault in the field winding. A second set of output contacts and a front panel indicator annunciate the detection of lower than normal resistance across the field winding and ground.

Replacement of an ABB 64F with the BE1-64F is simplified because the panel cutout and drilling pattern for the BE1-64F matches that of the ABB 64F.
