■ Product Overview

The transformer bushing on-line monitoring device is composed of bushing end screen adapter and monitoring host. The specially designed end-screen adapter integrates a core current measurement sensor, which can not only ensure reliable grounding of the end-screen, but also achieve high-precision leakage current measurement. The monitoring host adopts high-speed digital signal processor to realize real-time and accurate measurement and calculation of leakage current and three-phase current vector sum, and has many functions such as local display and alarm.
