35kV Distribution Line Single-Phase Ground Fault Handling
Since the neutral voltage is non-zero, current flows through the arc suppression coil, and “busbar grounding” signals may appear depending on the magnitude of the displacement voltage.

What is the role of a grounding bus bar?
When a fault occurs (e.g., a live wire touches a metal appliance casing), the fault current flows through the grounding system, including the bus bar, to ground.
High Voltage Busbar Protection
HIGH VOLTAGE BUSBAR PROTECTION The protection arrangement for an electrical system should cover the whole system against all possible faults. Line protection concepts, such as overcurrent and
