1. The importance of zinc oxide surge arrester tester
Zinc Oxide Arrester can easily cause faults due to its aging, moisture, etc. during operation. This will lead to the main equipment being unprotected, and it may happen in severe cases, which will affect the safe operation of the system. The Zinc Oxide Arrester Pretest must stop the main equipment, which will affect the operational reliability of the equipment. At times, the main equipment cannot be stopped due to the limitation of the operating mode, and the arrester cannot be pre-tested on time. Therefore, the live test and on-line monitoring of the zinc oxide lightning arrester are particularly important.
2. Zinc Oxide Arrester Charger Tester Zinc Oxide Arrester Charge Test Purpose
Using the live measurement of the zinc oxide arrester, the ratio of the arrester's resistive current to the total leak current is measured, that is, the resistive current component of the zinc oxide arrester to determine the moisture and aging conditions of the arrester. When the zinc oxide surge arrester ages in the valve plate and is subjected to thermal and shock damage and internal moisture, the active loss of the zinc oxide arrester is intensified. That is, the resistive current component in the leakage current of the arrester is significantly increased, and thus is generated inside the zinc oxide surge arrester. The heat causes the zinc oxide surge arrester valve to further deteriorate, creating a vicious circle and destroying the internal stability of the zinc oxide arrester. The oxidized arrester is used to measure the active component lively, and the problematic zinc oxide arrester is found in time to prevent equipment failure in the bud.
3. Zinc Oxide Lightning Arrester Tester Affects Zinc Oxide Arrester Charge Test Factors
There are many factors affecting the live test of zinc oxide surge arresters, including inter-phase interference, test methods, and surface contamination. The surface contamination can be solved at the scene by cleaning the surface of zinc oxide surge arresters. Here, the interphase interference within the interval and the influence of the test method on the measurement are mainly excluded.
