Annual shutdown preventive maintenance and HT equipment servicing, testing and commissioning
Some checks can only be done with the equipment dead. An annual shutdown is the chance to open up switchboards, service the breakers, test the protection and fix what the year's inspections have found.
Shutdowns are planned in detail beforehand so the power-off window is as short as possible. We draw up the sequence with you and your building management, and restore supply in a controlled order.
