Abstract

This paper is mainly to develop a measurement standard for insulation parameters on-line moni- toring 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 technol- ogy; 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. KEYWORD: Relative dielectric loss, Energized test, Measurement standards
