1. Voltage problemReason: High voltage will cause the transformer to be over-excited and the sound will become louder and sharper, which will directly seriously affect the noise of the transformer.Judgment method: First look at the low-voltage output voltage. Do not look at the voltmeter on the low-

There are a large number of "energy storage elements" in the power system, which are capacitors that store electrostatic energy and inductance that store magnetic energy. These components form a variety of oscillation circuits. During normal operation, these oscillation circuits are damped

1 IntroductionIn the process of electric energy transmission and distribution, power transformers are the core of energy conversion and transmission. They are the only way for all walks of life in the national economy and thousands of households to source energy. They are the most important and crit

The technology of live cleaning and maintenance of electric power and electrical equipment is generally a technology for cleaning power and electrical equipment that does not have power outages or has periodic power outages. Cleaning is carried out by professional cleaning personnel using profession
