Counters And Monitors

As a special supporting product of the arrester, the counter is used in series with the arrester to record the working condition of the arrester. It is especially suitable for lightning arresters used in 35kV and above power stations and lines, and can also be used with three-phase combined over-voltage protection products.

The structure of the counter can be divided into outdoor dial type and split type in the cabinet; In terms of function, it can be divided into simple counting type and additional current monitoring type; The components can be divided into valve sampling type and transformer sampling type. The above counters are produced by our company.


Usage: Environmental Conditions

1. Ambient temperature: not higher than +40 ºC, not lower than - 40 ºC;
2. Rated frequency: 50Hz or 60Hz;
3. The voltage applied to the arrester for a long time shall not be higher than the continuous operation voltage of the arrester;
4. Maximum wind speed: 35m/s;

Overall Dimensions


For detailed description and usage of the counter, please refer to our special counter instruction manual. If the arrester is equipped with a counter, the letter "J" shall be added after the standard model (the product with an additional current monitoring function shall be indicated by the letter "JCQ"). For example, YH5WS-17/50J indicates that a counter is installed on YH5WS-17/50 arrester.
