This section contains information on inspecting and performing preventive maintenance on HVL/cc Metal-Enclosed Switchgear. Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS-2011, or CSA Z462. It may also be useful to others. It will help managers, engineers and others to understand their responsibilities and duties in the selection, use, operation and maintenance of. All LV switchboards should be completely cleaned, vacuumed, and given a thorough visual check on the inside and out. Verify that any installed electronic surge protection is still functional. Be sure to check the rating as well as the continuity of the fuse in the control circuit. As needed. This utility procedure classifies maintenance tasks for miscellaneous electric overhead (OH) and underground (UG) equipment, including capacitor banks, fault indicators, interrupters, reclosers, voltage regulators, Supervisory Control and Data Acquisition (SCADA) and Primary Distribution Alarm and. High voltage systems are pivotal in the realm of electrical engineering, primarily tasked with the generation, transmission, and distribution of electricity. Typically defined as systems operating at voltages above 1,000 volts AC and 1,500 volts DC, these systems are essential for facilitating the. The only way to combat natural ageing of equipment while adhering to management requirement is correct maintenance, which allows prevention of faults in the electrical apparatus and components installed.
