Surge arrester regularly check

The insulation resistance of the polymer housed surge arrester should be checked regularly. The 2500 volt insulation shaker is used for the measurement, and the value obtained from the side is compared with the previous one. If there is no significant change, the operation can be continued. When the insulation resistance drops significantly, it is usually caused by poor sealing and moisture or short circuit of spark gap. When it is lower than the qualified value, it should be tested for characteristic; when the insulation resistance is significantly increased, it is generally due to poor contact or fracture of internal parallel resistance. And spring relaxation and separation of internal components.

In order to detect invisible defects inside the valve arrester in time, a preventive test should be conducted before the annual thunderstorm season.
