Abstract: Rotating bridge rectifier is the integral part of the power unit, the quality and running status of which is very important for the safe and stable operation of generator units. However, there is no proven detection and alarming device for rotary rectifying element in the domestic market. In this paper, an introduction is made to the NES6131 rotating rectifier element detection and alarm device newly developed by NARI TECH. Through a series of field tests in the No.2 generator units of Tianwan Nuclear Power Plant, the NES6131 is fully functional, reliable, accurate and high portable, and is especially suitable for large brushless generators which is equipped with position detection coil and current detection coil.

Key words: rotating bridge rectifier, NES6131, detection, alarming
