  • Power Transformer Infrared Inspections | Fluke

    Mar 29, 2021 · Properly 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.
