Safeguarding High-Frequency Step-Up Transformers from Moisture Moisture can seriously compromise the performance of high-frequency step-up transformers , potentially leading to insulation breakdown or even catastrophic failures. To ensure transformers remain operational, it is crucial to implement moisture control strategies. One such strategy involves securing the transformer with a cover and using a vacuum pump to evacuate moisture at the end of the workday. This step removes any free water from the transformer body. The next day, dry nitrogen or dry air should be introduced to further dry the system before putting it into operation. After maintenance, high-frequency step-up transformers can usually be resumed after 24 hours of hot oil circulation. In addition to moisture evacuation, daily rainproof measures should be observed. After every workday, a hot oil spray drying procedure should be carried out to prevent moisture accumulation. The drying process typically takes...
