NDFDC-III Surge Arrester Discharge Counter Tester (Handheld Type)

Product Introduction

       Due to poor sealing, the lightning arrester counter may allow moisture and water to enter during operation, causing internal components to rust and preventing normal operation. The reliability of the counter's operation is crucial for the power system, as it records the number of lightning strikes the arrester experiences during normal operation. It provides important data for power system personnel to conduct targeted inspections of the arrester. Therefore, the "Regulations" stipulate that it should be inspected at least once a year.

       The lightning arrester counter tester is used to verify the reliability of various lightning arrester counters. It is suitable for valve-type arresters (including silicon carbide ordinary valve-type (FZ and FCD) and silicon carbide magnetic blow valve-type (FCZ and FCD)) and zinc oxide arresters to check and verify the discharge action of the discharge recorder. The instrument complies with the requirements of the power industry standard DL474.5-92 "Field Insulation Test Implementation Guidelines - Arrester Tests" and is suitable for testing in various conditions such as power plants, substations, repair workshops, and laboratories. This instrument adopts a handheld design with an attractive appearance and convenient portability. It replaces traditional bulky testing instruments and methods for the action tests of lightning arrester counters, making it highly popular among professionals.
