Product Description
■ Product Overview
This instrument is developed and manufactured using phase‑lead processing technology and data‑transfer algorithm technology. It falls between the two major categories of online and portable devices. , The method of use is portable. , It operates in online mode. This instrument features high detection sensitivity, strong anti-interference capability, compact size, light weight, and ease of use. When locating ground faults in DC systems, , No need to disconnect the power supply. , It enables the localization of ground fault points. The instrument can measure the grounding resistance of DC systems, providing a practical, reliable, and highly accurate detection tool for identifying and locating ground faults in power DC systems.
