What is the transformer temperature rising test ?
When the temperature of transformer accessories exceeds its allowable range for a long time, even the transformer oil temperature is 10℃ higher than normal or the temperature is still rising, the insulation of transformer will be easily damaged and broken down by high voltage,causing failure or accidents . In order to ensure the normal work and service life-span of transformer, it is very important to evaluate the transformer heat up. Let’s discuss the transformer testing for temperature rising in the article .
