Multiparameter Current Protections Against Ground Faults in 6 – 10 kV Cable Networks1

  • Published:
Power Technology and Engineering Aims and scope

Zero sequence current protections are most widely used for protection from single-phase ground faults in distributed 6 – 10 kV cable networks operating with an isolated neutral. Multiparametric operating principles for current protections are proposed which enhance their sensitivity in stable operation and during the most hazardous arc intermittent ground faults.
