The phase time overcurrent element can provide a desired time-delay operating characteristic versus the applied current or
be used as a simple Definite Time element. The phase current input quantities may be programmed as fundamental phasor
magnitude or total waveform RMS magnitude as required by the application.
Two methods of resetting operation are available: “Timed” and “Instantaneous” (refer to the Inverse
TOC Curves Character-
istic
sub-section earlier for details on curve setup, trip times and reset operation). When the element is blocked, the time
accumulator will reset according to the reset characteristic. For example, if the element reset characteristic is set to “Instan-
taneous” and the element is blocked, the time accumulator will be cleared immediately.
The
PHASE TOC1 PICKUP
setting can be dynamically reduced by a voltage restraint feature (when enabled). This is accom-
plished via the multipliers (Mvr) corresponding to the phase-phase voltages of the voltage restraint characteristic curve (see
the figure below); the pickup level is calculated as ‘Mvr’ times the
PHASE TOC1 PICKUP
setting. If the voltage restraint feature
is disabled, the pickup level always remains at the setting value.
