This circuit breaker maintenance form helps technicians and inspectors record critical checks for power distribution equipment. Use it to capture mechanism checks and timing tests, inspect gauges and pressure switches, reset counters, and review the control cubicle, door seals, and hardware. Document SF6 gas analysis including dew point, acidity, air content, purity, and pressure, or record oil levels and moisture for oil filled units. Check interlocks, housings, ductor test results, cable end boxes, CT condition and insulation resistance, terminations and earthing, and bushing condition and torque. Suitable for scheduled maintenance of HV circuit breakers in substations and industrial facilities.
