Work items, definitions, and references shall comply with the latest edition of the NETA Maintenance Testing Specifications. Below is a list of electrical equipment that shall be maintained, tested, and ultimately reported.
TRANSFORMERS:
Transformers over 500KVA shall be cleaned externally, inspected for overheating via thermal scan, and inspected for any damage to housing, connection points or insulation.
Liquid filled transformers shall have cooling liquid tested to meet manufacturer s recommendation.
Dry transformers will be cleaned externally, and inspected for overheating via thermal scan.
ELECTRICAL GEAR (including, but not limited to, Switchgear, Switchboards, Distribution Panels, Motor Control Centers, and all related equipment):
Use lint free rags to clean conductors, contact points between circuit breakers and main buss bars, buss bars, and the interior of the electrical equipment. Use a vacuum cleaner to remove large debris. (compressed air is not to be used for this purpose). Visually inspect for any obvious signs of overheating, misaligned contacts, insulation damage, or lose lugs.
Lubricate all moving parts according to manufacturer s recommendation.
Test and exercise circuit breakers located in switchgear, switchboards, and distribution panels to ensure operation under overload conditions.
Inspect and tighten ground connections. Test ground resistance for entire facility grounding system.
Identify hot spots in electrical equipment via thermal scan. Tighten problem connections to meet manufacturer s recommendations using a torque wrench or other approved device.
Calibrate and maintain adjustable protective relays.
Test all control systems equipment for proper operation after maintenance is performed and before placing them back in normal service.
AUTOMATIC TRANSFER SWITCHES
Use lint free rags to clean conductors and contact points. Use a vacuum cleaner to remove large debris. (Compressed air is not to be used for this purpose). Visually inspect for any obvious signs of overheating, misaligned contacts, insulation damage, or lose lugs.
Lubricate all moving parts according to manufacturer s recommendation.
Inspect and tighten connections.
Test for proper switching operation.
DISCONNECTS
Use lint free rags to clean conductors and contact points. Use a vacuum cleaner to remove large debris. (compressed air is not to be used for this purpose). Visually inspect for any obvious signs of overheating, misaligned contacts, insulation damage, or lose lugs.
Lubricate all moving parts according to manufacturer s recommendation.
Inspect and tighten connections.
Test for proper switching operation.
Additional notes:
All electrical work is executed with all proximate energized circuits de-energized when and where possible.
When a planned electrical outage cannot be accomplished the following requirements are mandatory for working on energized circuits.
Full personal protective equipment (PPE) will be available and worn by qualified electricians according to the guidelines outlined in NFPA 70E.
A written energized electrical work permit shall be obtained from the safety office prior to any energized work. (sample included Appendix 1)
This work may have to be done after regular working hours or on weekends.
Provide complete written report of the work. Information shown in the report shall be as following:
