  • Error is proportional to the mutual coupling factor K0m
  • • The error increases with the parallel line earth current in relation to the relay current
  • • The relay underreaches when IEP is in phase with Iph + KN . IE . For a remote end terminal fault, this underreaching effect can be as high as 25%. The distance protection zone reaches vary with the switching state of the parallel line configuration.
  • We consider the three most common operation modes: 1. Case 1: Parallel line out of service and earthed at both ends 2. Case 2: Parallel line switched off and not earthed or earthed only at one line end 3. Case 3: Both lines in service. The reach of the distance protection zone 1 will be different depending on the operation condition of the parallel line.
  • Compensation of the mutual zero sequence impedance of parallel circuit can be achieved by appropriate selection of zero-sequence compensation factor KN when parallel line can be in service, out of service, or out of service and earthed at both ends.
  • Five zone distance protection, mho characteristic function (ZMHPDIS) can compensate for the influence of a zero sequence mutual coupling on the measurement at single phase-to-earth faults in the following two ways, by using:
  • • Different setting values that influence the earth -return compensation for different distance zones within the same group of setting parameters.
  • • Different groups of setting parameters for different operating conditions of a protected multi circuit line.
