Abstract
The main purpose of this work is to present a new resistive sensor for online assessment of the insulation condition of high voltage capacitive bushings. Capacitive bushings are one of the most critical components of power transformers and online monitoring can prevent explosions, that may result in damages ang power outages. The proposed sensor can online determine the absolute values of the capacitance with absolute errors that enable a qualitative analysis. Future studies may use this sensor to also determine the resulting sum of currents through three phase sensors and the insulations’ power factor.
