Switchgear, Transformer, Incoming Power Systems Testing, Calibration, Replacement Equipment, Services and Repairs General: This contract provides engineering, inspection, calibration, repair and testing services related to electrical power and control equipment/systems. Visual and Mechanical Inspection Inspect physical and mechanical condition, including evidence of moisture and/or corona. Verify tightness of accessible bolted electrical connections Test all electrical and mechanical interlock systems for correct operation and sequencing. Verify correct barrier and shutter installation and operation. Exercise all active components and confirm correct operation of all indicating devices. Inspect contactors: Verify mechanical operation. Inspect and adjust contact gap, wipe, alignment and pressure in accordance with manufacturer's published data. Verify appropriate contact lubricant on moving current-carrying parts. Verify appropriate lubrication on moving and sliding surfaces. Electrical Tests Perform insulation-resistance test on contactor(s), phase-to-ground, phase-to-phase, and across the open contacts for one minute. Perform vacuum bottle integrity test (over-potential), if applicable, across each vacuum bottle with the contacts in the open position in strict accordance with manufacturer's published data. Do not exceed maximum voltage stipulated for this test. Perform a contact-resistance test.
