Using electrical equipment for aging has a big safety risk. Therefore, judge the degree of aging of electrical equipment, avoid accidents and maintain the stability of the power system. How to determine the service life of electrical equipment? HVHIPOT? editor introduce everyone to know 3 methods as following

1, The electrical equipment in the building, based on the delivery time, the use of the electrical equipment is established, and the aging is expected. For example, the house has not been renovated newly renovated, the house built on the power line is still the power line can be based on the use of time, generally based on the service life of the specific electrical product, wire aging is expected.

2. Observe the surface of electrical equipment to determine whether it is aging. If there is no real connection point, thread release, damage to the insulation layer, the phenomenon of closing the fulcrum insulation, or strange odors occur when using electrical equipment, etc., often means that the equipment has aged and should be stopped immediately.

3, According to the use of the electrical equipment environment (including temperature, chemical corrosion and current load level, etc.) to judge. For example, if electrical equipment is used in a constant temperature, constant humidity, and no chemical corrosion environment, the number of electrical equipment, based on the date marked on the factory, is estimated to have been used for years.
