Overload Protection: Monitors load current using current transformers and relays to prevent transformer damage due to prolonged overload.
Short Circuit Protection: Uses fuses or circuit breakers to quickly disconnect the circuit in the event of a short circuit, protecting the transformer from high current surges.
Temperature Protection: Monitors the internal temperature of the transformer using temperature sensors; triggers an alarm or trips when the temperature exceeds a set value.
Grounding Protection: Detects grounding faults at the transformer's neutral point or casing to prevent leakage or electric shock accidents.
Overvoltage Protection: Uses surge arresters or overvoltage relays to suppress damage to the transformer from lightning or operational overvoltages.
Undervoltage Protection: Cuts off power when the voltage is too low, preventing the transformer from operating under abnormal conditions.
