Post-Fault

869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL
J1(J2,K1,K2) Fault Phase la(lb,lc)
Range: 0.000 to 46.000 x CT in steps of 0.001
Default: 0.000 x CT
J1(J2,K1,K2) Fault Phase lg
Range:
For Ground CT: 0.000 to 46.000 x CT in steps of 0.001
For Sensitive Ground CT: 0.000 to 4.600 x CT in steps of 0.001
For CBCT: 0.000 to 15.000 x CT in steps of 0.001
Default: 0.000 x CT
The ground current magnitude setpoint range is dependent on the ground CT type as
defined in the Order Code options. For Ground CT, the magnitude is entered as a multiple
of the corresponding CT Bank GROUND CT PRIMARY setpoint. For Sensitive Ground CT,
the magnitude is entered as a multiple of the corresponding CT Bank SENS GROUND CT
PRIMARY setpoint. For CBCT, the magnitude is entered as a multiple of 1A.
J1(J2,K1,K2) Fault la(lb,lc,lg) Angle
Range: -359.9° to 0.0° in steps of 0.1
Default: 0.0°
The Post-fault state is intended to simulate a system that has tripped by replacing the
normal input parameters with programmed post-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.
