CDYH-K Series

CDYH-K Series

Description

CDYH-k impulse voltage generator is an on-site ready-to-install model for convenient transport and quick on-site installation. It is mainly used to test the ability of outdoor or field HV apparatus withstanding voltage peaks (transformer, switch, cable, inductor, insulator etc). It is designed for applications of research and routine test.
