Electroscope Test Stand

The MOEORW-W372N electroscope test stand is developed in strict accordance with the requirements of Preventive Test Regulations for Electric Safety Tools (Trial) (Guo Dian Fa [2002] No.777) and fully complies with national standards and DL740-2014 industry specification. This testing device is specially designed for functional performance inspection of 10kV–500kV high-voltage electroscopes used in all power industry sectors. It can complete three core standard tests for electroscopes: startup voltage detection, same-direction interference electric field test, reverse interference electric field test. The whole set is split into two size specifications to match different voltage grades, with adjustable sliding guide rails to precisely control electrode spacing, supporting two types of electroscopes (with/without extended contact electrodes) for standardized, repeatable laboratory preventive testing of safety tools.
