Data acquisition system design of partial discharge ultrasonic testing for power generation with stator-winding pattern

LIAO Jian-qing;Department of Physics & Electrical Engineering, Ningde Normal University;  
To improve timely and precise detection of the partial discharge detection of generators, a kind of ultrasonic testing data acquisition system has been developed. The system adopts a STC89LE52single chip microcomputer as the control core. This paper mainly introduces the system composition,voltage, current sampling circuits, the circuit design, and the realization of it. The system has the advantages of simple structure, strong anti-interference, good stability, and practical value.
