Abstract :
This paper describes the recent Brazilian experience at on-site Partial Discharges (PD) measurement and analysis in Power Transformers, including the development of IMA-DP (Instrumentation for Monitoring and Analysis of Partial Discharges), designed by Eletrobras to monitor High Voltage Equipment. The proposed system includes high speed digitizer cards on an industrial computer and is designed to operate offline or on-line, remotely logging statistical maps of PD over time. The goal of this project was to evaluate the performance of the operative state of power transformers of 138kV up to 500kV installed in the Brazilian electric power system.
