Abstract

The online monitoring devices for dissolved gases in insulating oil play a significant role in monitoring the operating status and pre-diagnosis of latent faults in oil-filled electrical equipment such as transformers and reactors. To quickly evaluate the reliability and long-term stability of products from different manufacturers with different detection principles and process designs, and to effectively utilize the devices’ online monitoring capabilities, this article proposes a method for accelerated degradation testing of such equipment based on comprehensive research and analysis. Additionally, a corresponding on-site reliability testing platform has been established using a retired transformer at a certain substation. The method and platform proposed in this article can be used to conduct fully automatic short-cycle continuous operation (time compression), intensive stress event impact (event compression), and other accelerated degradation tests on online monitoring devices for dissolved gases in insulating oil, automatically generating various reliability indicators using statistical methods.
