| Abstract: | Based on the standard DLT 987--2005, technology indexes of zinc oxide arrester resistive current tester calibration were proposed. The hardware circuit design method of bridge driver and Howland constant-current source was given, and the attentions should be paid to the design were pointed out. The precision and stability of output signal could meet the requirement based on the experimental data. |
