JSZ-8 surge lightning arrester measuring counter

Used to monitor the discharging action times and operation condition of surge arrester or overvoltage protector and give alarm.

Arrester Discharging Monitor Counter

1. Use: It is a high voltage electric equipment used to monitor arrester (or over-voltage protector)'s discharging action amount. What's more, it can also monitor the operation conditon and give alarm to the failure product so that the user can make it stop operating in time to avoid further damage to the whole electric system.

2. Components: non-linear varistor, Electromagnetic counter

3. Common Models: Nowadays, as the state power industry greatly develps, the market of discharge monitor is larger and larger. At the same time, we make further research and develop from the function. The most common models are JS-8, JSY-10/600, JCS-3.

4. Technical Parameter: 

1.  type: JSZ-8
