What Is the Use of Zinc Oxide Lightning Arrester Tester?

The main function of the zinc oxide lightning arrester tester is to detect and maintain the performance and safety status of the zinc oxide lightning arrester. Through a series of tests and measurements, the tester can determine key parameters such as the lossless discharge current, residual voltage, and leakage current of the lightning arrester, which directly affect the protection capability and lifespan of the lightning arrester. Through regular inspections, potential issues such as moisture in the insulation and aging of valve plates inside lightning arresters can be detected in a timely manner, ensuring the normal operation of lightning arresters and protecting power systems and electrical equipment from lightning damage.

The principle of the live testing instrument for lightning arresters is mainly to evaluate the performance of lightning arresters by measuring their resistive and capacitive currents. During the testing process, the instrument will input the signal from the electric field induction sensor and the current signal from the lightning arrester. After Fourier transform, the fundamental wave of the electric field, the peak value of the fundamental wave of the current, and the angle of the current electric field can be obtained. The peak value of the fundamental wave of resistive current can be calculated by projection method and is usually used to measure the performance of lightning arresters. ‌
