The surge arrester discharge counter tester is used to verify the reliability of the operation of various surge arrester counters.The reliability of the counter operation is very important for the power system, as it is an important parameter for recording the number of lightning strikes that the surge arrester receives during normal operation. It can provide power system staff with important evidence for targeted inspection of surge arresters. This instrument is mainly used for high-voltage surge arresters above 35kV.
Main Features:
This product is mainly used for the counting operation of high-voltage surge arresters above 10KV. Its working principle is mainly based on the standard impulse current method: the impulse current generator produces an 8/20μs, 100A impulse current wave applied to the operation counter for 3 to 5 consecutive tests, each time it should operate normally, with an interval of not less than 30s between each test. After testing, the recorder should be reset to 0.
>It has the characteristics of small size, light weight, easy to carry, high reliability, and simple operation.
Main Technical Indicators:
>Output current: ≥100A
>Output impulse current waveform: 8/20μs
>Input voltage: AC 220V ±5% 50Hz
