Product Description

    HY5W-3/10 Zinc Oxide Arrester with Electrical Switchgear Euipment





The CPD test is similar to the general pressure test, except that the CPD voltage is not fixed, but is raised to the lightning arrester discharge. It is advisable to cut the power supply at the rate of 3 ~ 5 000 volts per second, so it should be installed in the test circuit.



Testing of ZnO arrestors MOA is a new type of overvoltage protection equipment, which has better protection performance than silicon carbide lightning arrester, so it is widely used in power system. Pilot projects, cycles and requirements are specified in the precautionary test protocols for electrical equipment. The test of ZnO lightning arrester, in addition to the insulation resistance, base insulation resistance, discharge counting, and other conventional test items, also to measure the DC voltage 1MA voltage and 0.75 MA voltage leakage current.



The purpose of measuring the leakage current at 0.75 times DC voltage is to detect the change of the long-term allowable working current, which should not be greater than 5 MiA, which is closely related to the life of the lightning arrester.
