10kV busbar phase A grounding
Generally, the busbar side of 10kV switchgear does not have a dedicated earthing switch. Phase-to-phase and phase-to-ground dimensions are the same because switchgear used on ungrounded or impedance grounded systems will have phase to phase voltage between the unfaulted phases and ground during a ground fault condition. It is not possible to test every configuration of bus used in. After a 10 kV ground fault, the bus VT detects no current but develops zero-sequence voltage and increased current in the open delta. Prolonged operation can damage the VT. Therefore, this paper studied the flexible grounding system consisting of.
