[0002] Power repair is an emergency treatment action for power failures in order to restore power supply as soon as possible after a power facility fails. It is a key link to ensure the normal production and life of power users, and can reduce the impact of failures on the economy and society. Through rapid response and effective repair, power supply can be quickly restored, power outage time and power outage losses can be reduced, and power supply reliability can be improved. Before performing electrical work, the power supply must be cut off and a tester must be used to test the power to ensure that the power supply has been disconnected to ensure the safety of the repair personnel. During the repair process, priority should be given to ensuring the power supply of important users and key facilities, and the power outage sequence and repair process should be reasonably arranged to shorten the power outage time.
