All grounds MUST be hooked up for normal operation regardless of control power supply type. WARNING GE Power Management 469 Motor Management Relay...
Page 32: Phase Current Inputs
For example, in mining applications where earth leakage current must be measured for personnel safety, primary ground current as low as 0.25 A may be detected with the GE Power Management 50:0.025 CT. Only one ground CT input tap should be used on a given unit.
Page 33 (see Section 1.2: SPECIFICATIONS on page 1–5). The 469 measures up to 25 A of primary ground current if this tap is used in conjunction with the GE Power Management core balance CT. The zero-sequence connection is recommended. Unequal saturation of CTs, size and location of motor, resistance of power system and motor core saturation density, etc., may cause false...

5 hours. • Since the rotor cools faster when the motor is running, a reasonable setting for the running cool time con- stant might be half the stopped cool time constant or 150 minutes. GE Power Management 469 Motor Management Relay...
Page 291: D.1.1 Ground Fault Cts For 50:0.025 A
D.1.1 GROUND FAULT CTS FOR 50:0.025 A CTs that are specially designed to match the ground fault input of GE Power Management motor protection relays should be used to ensure correct performance. These CTs have a 50:0.025A (2000:1 ratio) and can sense low leakage currents over the relay setting range with minimum error.
Page 292: D.1.2 Ground Fault Cts For 5 A Secondary Ct
For low resistance or solidly grounded systems, a 5 A secondary CT should be used. Two sizes are available with 5½” or 13” × 16” windows. Various Primary amp CTs can be chosen (50 to 250). GCT5 GCT16 DIMENSIONS DIMENSIONS 469 Motor Management Relay GE Power Management...
