Since undertaking the electrical equipment testing task of the company, the Electrical Instrument Room of the Equipment Research Institute (hereinafter referred to as the testing unit) has successively carried out power equipment status monitoring services such as infrared imaging testing, power quality testing, partial discharge testing, and motor testing. Through the development of the above businesses, the testing unit expects to gradually provide high-quality and comprehensive services to equipment users.
The purpose of power equipment status monitoring is to use effective detection methods and analytical diagnostic techniques to timely and accurately grasp the operating status of equipment, ensuring its safety, reliability, and economic operation. So power equipment status monitoring should be a closed-loop process of detection, analysis, processing, feedback, and retesting. The testing unit accumulates data year after year in this process, summarizes experience, masters the operating characteristics of electrical equipment, and ultimately achieves the goal of long-term operation of electrical equipment together with equipment users.
Only when the detection process forms a closed loop, can the detection methods provide guidance for the operation of the equipment. That is to say, after the testing unit undertakes the testing business, it hopes that the equipment user can provide the testing unit with the rectification method and the results after on-site rectification based on the problems found during the testing. However, some device users do not attach enough importance to the test results and fail to provide timely processing information to the testing units, which is not conducive to the testing units summarizing the experience of equipment operation. Since no problems have been found in the motor testing business, this article only provides explanations for three complete cases of the three testing methods, hoping to draw sufficient attention from the equipment management department and equipment users to the closed-loop management of power equipment status monitoring, so as to achieve the goal of safe and stable long-term operation of the equipment.
