Arrester Discharge Counter Calibration Instrument Manufacturer
The arrester discharge counter calibration instrument is used to verify the reliability of the operation of various arrester counters. The reliability of counter operation is very important for the power system, as it is an important parameter for recording the number of lightning strikes on arresters during normal operation. It provides important basis for power system staff to conduct targeted inspections of arresters. This instrument is mainly used for high-voltage arresters above 35kV.

Main Features:
This product is mainly used to check the counting operation of high-voltage arresters above 10KV. Its working principle is mainly based on the standard impulse current method: apply the 8/20μs, 100A impulse current wave generated by the impulse current generator to the action 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.
