China GDHG-106B CT/PT Analyzer Manufacture and Factory

GDHG-106B CT/PT Analyzer

Brief Description:

GDHG-106B is a multifunctional tool specially designed for analyzing current transformers and voltage transformers of protection or measurement use. The operator only needs to set values for test current and voltage, the instrument will automatically boost voltage and current, and then show test results in a short time. Test data can be saved, printed, and uploaded to PC through USB interface.
