The residual current device (RCD) tester is primarily used to measure the RCD’s tripping current, non-tripping current, and tripping time. The test current range is 0–500 mA, divided into ten steps, while the timing range is 0–799 ms. It features a 16-character blue-backlit LCD display. This handheld instrument is compact, lightweight, and easy to carry, making it the ideal testing tool for on-site or laboratory testing of various RCDs.

A customer in Shanxi has purchased one set of our MCYZ-308 zinc oxide surge arrester tester!
The live-testing instrument for zinc oxide surge arresters is used to evaluate the electrical performance of each phase of a zinc oxide surge arrester (MOA). This instrument is suitable for on-site live testing of zinc oxide surge arresters across all voltage levels, as well as for factory and acceptance tests conducted in the laboratory under de-energized conditions. By measuring parameters such as total current and resistive current, it can promptly detect hazardous defects, including internal insulation moisture absorption and valve element aging, in zinc oxide surge arresters.
