Research on developing a measurement standard for insulation parameters on-line monitoring device

Abstract

This paper is mainly to develop a measurement standard for insulation parameters on-line monitoring device. The paper achieves measurement standards for the Voltage, current, capacitance and dielectric loss data of insulation parameter monitoring device by voltage, current sync source generated by DDS technology; precision voltage source, constant current source module composed by op amp, voltage transformers and current transformers Group; Capacitive analog reference voltage and leakage current equipment. After being calibrated by the national legal metrology bodies, the metering standard technical indicators have reached the design requirements.
