De-Energized Maintenance
De-energized maintenance is used to maintain electrical systems by shutting them down completely to perform maintenance tasks mandated during de-energized maintenance include testing of overcurrent protection devices, relays, insulators, connections, and cables. Additionally, the equipment is exercised, cleaned, lubricated, and torqued per the specifications provided by OEM, NFPA, and NETA. During de-energized maintenance, thermal, code and safety issues identified during energized maintenance can be corrected without exposure to energized components.
