Inspect physical and mechanical condition. Inspect anchorage, alignment and grounding. Verify that all maintenance devices are available for servicing and operating the breaker. Clean the unit. Inspect vacuum bottle assemblies. Measure critical distances such as contact gap as recommended by the manufacturer. If recommended by the manufacturer, slow close/open the breaker and check for binding friction, contact alignment, contact sequence and penetration. Perform all mechanical operation tests on the operating mechanism in accordance with manufacturer’s published data. Inspect bolted electrical connections for high resistance using one of the following methods: a. Verify tightness of accessible bolted electrical connections by calibrated torque‐wrench method in accordance with manufacturer’s published data. In the absence of manufacturer’s published data, use Table 100.12 Verify cell fit and element alignment. Verify racking mechanism operation. Inspect vacuum bellows operation. Use appropriate lubrication on moving current‐carrying parts and on moving and sliding surfaces. Electrical Tests: 1. Perform insulation‐resistance tests for one minute on each pole, phase‐to‐phase and phase‐to‐ground with circuit breaker closed and across each pole with the breaker open. Apply voltage in accordance with manufacturer’s published data. In the absence of manufacturer’s published data, use Table 100.1. 2. Perform a contact/pole‐resistance test. 3. With breaker in a test position, perform the following tests a. Trip and close breaker with the control switch. b. Trip breaker by operating each of its protective relays. c. Verify mechanism charge, trip‐free, and antipump functions. 4. Perform a vacuum bottle integrity (overpotential) test across each vacuum bottle with the breaker in the open position in strict accordance with manufacturer’s published data. Do not exceed maximum voltage stipulated for this test. Provide adequate barriers and protection against x‐radiation during athis test. Do not perform this test unless the contact displacement of each interrupter is within manufacturer’s tolerance. Be aware that some dc high‐potential test sets are half‐wave rectified and may produce peak voltages in excess of the breaker manufacturer’s recommended maximum. 5. Test Instrument transformers in accordance with Section 7.10. PROTECTIVE RELAYS, ELECTROMECHANICAL AND SOLID‐STATE Visual and Mechanical Inspection: 1.
