Monitoring of Transformers check for leaks

Sep 21, 2016Inspect the bushing carefully for oil leaks. Check the oil level in the bushing by viewing the liquid through the oil-sight glass or by observing the oil level gauge. If the level gauge is equipped with a pointer, document its position, as the level should vary slightly with temperature changes.

  • Power Transformer Infrared Inspections | Fluke

    Apr 29, 2020Properly functioning cooling tubes are critical to keeping transformers from overheating. Transformers are especially susceptible to overheating because as they step up or step down voltage levels between circuits, energy is lost as heat in the core and windings. That heat can build up damaging insulation and leading to transformer failure.

  • White Paper: A new method for detecting transformer air leaks

    With the increased use of sealed transformers, the issue of air leaks as a source of oxygen has grown in importance. Such air leaks are often caused by embrittlement of gaskets or the rubber bag. In order to maximize a transformers operational life its oxygen levels should remain as low as possible. Monitoring that proper sealing is maintained against ambient air ingress through total gas pressure measurement
