Dielectric power equipment on the dielectric loss: transformer ceramic casing dielectric loss, voltage transformer dielectric loss, cable dielectric loss, capacitance dielectric loss, etc., the size of the dielectric loss and the ambient environmental temperature and humidity is directly proportional to the temperature and humidity of the problem, because humidity, humidity, the larger the error will be the larger the test temperature of different equipment, humidity requirements are different.
The test is measuring the ambient temperature, humidity, and then the data of the test is converted.
