Fault - GE 850 Instruction Manual

TESTING

Fault

9–28
JK Prefault Phase la(lb,lc):
Range: 0.000 to 46.000 x CT in steps of 0.001 x CT
Default: 0.000 x CT
Phase current magnitudes are entered as a multiple of the corresponding CT Bank
PHASE CT PRIMARY setpoint.
JK Prefault la(lb,lc) Angle:
Range: -359.9° to 0.0° in steps of 0.1
Default: 0.0°
The Fault state is intended to simulate the faulted operating condition of a system by
replacing the normal input parameters with programmed fault values.
Voltage magnitudes and angles are entered as Wye values only. The voltage setpoints are
not available if the corresponding VT Bank PHASE VT CONNECTION setpoint is Delta.
Voltages are set in secondary VT units.
The CT and VT Bank availability is dependent on the installed Order Code options.
