5.4.3.2 PHASE INSTANTANEOUS OVERCURRENT UNIT- PHASE IOC (50PH/ 50PL)
The 50P phase instantaneous overcurrent unit has a setpoint range from 0.05 A to 160 A, which can be set as
instantaneous or timed, with a timer selectable between 0.00 and 900 seconds. The phase current input quantities may be
programmed as Fundamental phasor magnitude or total waveform RMS magnitude as required by the application. The unit
incorporates a reset time selectable between 0 and 900 seconds.
This unit incorporates a block input for disabling the pickup and trip signals. The logic outputs are the pickup and trip flags
independent for each phase, and general pickup and trip flags for the unit.
Table 5–39: 50PH/50PL UNIT SETPOINTS
The snapshot event setpoint enables or disables the snapshot event generation for the phase instantaneous overcurrent
units.
