On-line Monitoring System and Double Regression Algorithm of Capacitor Voltage Transformer
2019
Ensuring safe and reliable operation of voltage transformers is of great significance. Temperature, humidity and other ambient factors may affects the dielectric loss and metering error of high voltage capacitor voltage transformer (CVT). In this paper, an on-line monitoring system which can obtain the dielectric loss, ratio error and angle error of CVT was introduced. Moreover, double regression algorithm which can calculate and predict the dielectric loss and metering error variation tendency of CVT was developed. It provides a new idea for on-line monitoring system application.
