1. A complete inspection of the equipment will be performed. The inspection shall include a thermo graphic survey (infrared scan), ultrasonic scan, and visual inspection. The thermo graphic survey will be conducted during periods of maximum possible loading with the current carrying conductors exposed for direct inspection of the components. Ultrasonic inspections will be conducted on all medium voltage equipment. Visual inspections shall note any evidence of equipment failure, component deterioration, unusual conditions, etc. Any discrepancies, “hot spots”, or evidence of corona, tracking, and arcing, etc., will be identified for immediate repair or scheduled for future correction and investigation. The organization will be responsible for removal /replacement of cover(s) for testing. 2. Electrical maintenance and testing will be performed on all emergency system generators. The generator will be inspected for damage, anchorage, grounding, and general condition. An insulation resistance test will be performed on the winding and a polarization index will be calculated. A power factor test will be performed on the windings. 3. A complete analysis of all transformer and circuit breaker insulating liquids will be performed. The sample will be taken with care to prevent spillage, using a drip pan if necessary. The oil sample containers will be new, sealed, and opened immediately prior to filling. Once filled, the sample container will be resealed with an identification label. This identification label will indicate the specific equipment that the sample was taken from. The analysis is permitted to be subcontracted and shall include dielectric breakdown, acid neutralization, specific gravity, moisture content, color, visual condition, and dissolved gas (500 KVA and over). All liquid filled transformers will be tested for polychlorinated biphenyls unless there is a visible label indicating prior testing. The insulating liquid level and nitrogen gas pressure will be verified and corrected as needed. 4. All UPS systems will be mechanically inspected, cleaned, electrically tested, and adjusted as needed. 5. All medium voltage distribution equipment (including any instrument transformers, protective relays, arrestors, grounding, etc.) and feeder cables will be fully inspected and tested in accordance with the most recent publication of NETA’s “Maintenance and Testing Specifications”.
