Application Of Ultra High Frequency On-line Monitoring System For Partial Discharge In Power Transformers

Local discharge is a transformer is insulated from the inside of one of the main reasons for deterioration. Of transformers in line with the local discharge monitoring could be timely and accurately determine the insulation within the state of the transformers, To prevent power transformer accident, To ensure the safety of power systems stable operation of the significance of.According to local discharging electricity UHF electromagnetic realize transformer fault detection and location is in recent years has proposed a new technology. Based on the analysis of domestic and international partial discharge on-line monitoring technology development, And partial discharge detection based on technical characteristics of UHF, Design the uhf partial discharge on-line monitoring system software and hardware, Completed monitoring system for substation 500kV huizhou installation and commissioning, Using the data of different discharge model test results, And UHF partial discharge detection system technology studies and analyzes the characteristics; Analysis results show that, UHF partial discharge detection system has strong anti-interference ability, the advantages of high precision.
