The topic research, standard device for power frequency lines parameters tester, can be used for calibrating the power frequency lines parameters tester. The equip functions involve: positive/zero sequence impedance, positive/zero sequence capacitance, etc. The topic introduces the working principle and composition of the standard device, focusing on the technology of virtual complex impedance and accurately amplitude control. The paper end gives the relevant specification and experimental data. The research of the standard device can be used to resolve the traceability of power frequency lines parameters tester.
