The effectiveness of using the calculated braking current for longitudinal differential protection of 110 – 750 kV shunt reactors

  • Published:
Power Technology and Engineering Aims and scope

The use of the function of effective current braking of the longitudinal differential protection of shunt reactors to offset current surges, which enables the sensitivity of differential protection to be increased when there are short circuits with low damage currents, is considered. It is shown that the use of the calculated braking characteristic enables the reliability of offset protection from transients to be increased when the reactor is connected, which is accompanied by the flow of asymmetric currents containing an aperiodic component.
