CDYH Series

CDYH Series

Description

CDYH impulse voltage generator is designed for applications of high voltage level, high capacity and high load requirements. It is mainly used to test the ability of HV apparatus withstanding voltage peaks (220kv and more voltage level transformer, switch, cable, inductor, insulator etc). It is designed for applications of research and routine test.
