phasetoground
Phase-to-ground fault is a type of short circuit in electrical power systems in which one live conductor makes contact with the earth or a grounded object. It is one of the most common fault types in power distribution and transmission networks, alongside phase-to-phase faults. Such faults can occur due to insulation failure, damaged cables, moisture, or contact with conductive objects after a fault.
During a phase-to-ground fault, current returns to the source through the earth, the grounding system, or a
Protection against phase-to-ground faults relies on protective relays and devices such as overcurrent protection, earth-fault protection,
