Tanδ Measuring Bridge

The system is used for HV cable, power transformer, HV switch and so on. It judges quality of test sample by HV Tanδ test to improve the quality. Computer in the device can process data automatically and display the results directly on the panel. It is high accurate, stable and easy-to-operate.

1.Accuracy: Cx±(reading×1%+1pF) other metal
