The power system runs a large number of power equipment, and the safe operation of power equipment is the premise of ensuring safe and reliable power supply. There may be some quality problems in the design and manufacture of power equipment, and damage may occur during installation and transportation, which may cause some latent faults. In the operation of power equipment, due to the influence of voltage, heat, chemical, mechanical vibration and other factors, its insulation performance will deteriorate, or even lose insulation performance, resulting in accidents.
According to the statistical analysis, more than 60% of power outage accidents in the power system are caused by equipment insulation defects. The deterioration of the insulation part of the equipment and the development of defects have a certain period of development. During this period, the insulation material will send out a variety of physical, chemical and electrical information, which reflects the change of the insulation state. This requires the electrical test personnel of the operation department to understand the insulation situation of the equipment before the equipment is put into operation or in the operation through the electrical test, so that in the early stage of the development of fault can be accurately and timely found and dealt with. Hence the name preventive trials.
Our company uses advanced testing equipment to provide customers with one-stop power equipment testing services, including offline testing after power failure and online monitoring services.
