Product Features

This series includes pointer‑type discharge counters, leakage current monitors and intelligent online recording instruments to satisfy different monitoring requirements for surge arresters. The mechanical counter clearly shows discharge times via dial pointer, while the pointer‑style monitor visually reflects leakage current value with mA scale. The intelligent digital recorder can store and display operation data for long‑term tracking. With compact circular housing and standard mounting holes, these devices adopt M10 series threaded terminals for high‑voltage connection and grounding connection, featuring easy installation and stable performance, suitable for long‑term outdoor operation together with various types of high‑voltage arresters.
