Development of Standard Device for Resistive Current Tester for Zinc Oxide Surge Arrester

摘要

The topic research, standard device for resistive current tester for zinc oxide surge arrester, can be used for calibration for resistive current tester for zinc oxide surge arrester. The equip functions involve total current, resistive component of current, capacitance component of current, active power, reference voltage, phase angle, harmonic component of current. The topic introduces the working principle and the core technology of the standard device, among them; the most innovative points are the "smoothing signal generation" and "traceability design".
