Significance of transformer drying oven in removing moisture
Transformer drying process removes traces of moisture in the transformer oil, besides enhancing insulation resistance and flashover voltage of transformers. The drying process is almost a part of production and is done regularly. Moisture management is an important aspect of transformer maintenance because moisture is connected to ageing and deterioration of the equipment. When the insulation gets damp and accumulates moisture, its functionality and heat transfer are affected. Insulation between various phases of the transformer is important attribute because it decides the lifespan of the transformer. Paper and insulating oils are insulation medium and insulation is affected when such paper absorbs water which in turn conducts electricity. If insulation of the transformer is not in prescribed levels, it results in surge of electricity which the transformer might not withstand and ultimately breakdown or collapse in failure. The transformer drying oven distinguishes pressure d
