5.4.3.2 Phase instantaneous overcurrent element- phase high/low
(50PH/ 50PL)
The Phase instantaneous overcurrent element has a setting range from 0.05 A to 160 A. It can be set as instantaneous or
timed, with the timer selectable between 0.00 and 900 seconds. The input quantities may be chosen as Fundamental
phasor magnitude or RMS magnitude as required by the application. The element incorporates a reset time selectable
between 0 and 900 seconds.
This element also incorporates a block input for disabling the pickup and trip signals. The logic outputs for the element are
the pickup and trip flags, independent for each phase, and general pickup and trip flags.
The snapshot event setting enables or disables the snapshot event generation for these elements.
