• Isolate the ACB breaker by opening the circuit and locking it in the open position

• Connect the load directly to the power source using a temporary cable

• Ensure that the temporary cable is rated for the load and is properly grounded

• Test the load to ensure that it is functioning properly before removing the temporar...read more

Transformer protection includes overcurrent, overvoltage, differential, earth fault, and thermal protection.

• Overcurrent protection prevents damage due to excessive current flow.

• Overvoltage protection prevents damage due to excessive voltage.

• Differential protection detects internal faults and isolates the transformer from the system.

• Earth fault protection detects faults between the transformer winding and earth.

• Thermal ...read more
