The negative-sequence time overcurrent element can be used to determine and clear unbalance in the system. The input
for calculating negative-sequence current is the fundamental phasor value.
Two methods of resetting operation are available; “Timed” and “Instantaneous” (see the Inverse TOC Curve Characteristics
section earlier for details on curve setup, trip times and reset operation). When the element is blocked, the time
accumulator resets according to the reset characteristic. For example, if the element reset characteristic is set to
“Instantaneous” and the element is blocked, the time accumulator clears immediately.
