A method for ultraviolet imaging detection and evaluation of stator end corona test

Abstract

This invention discloses a method for ultraviolet imaging detection and evaluation of stator end corona testing, belonging to the field of corona detection technology. Its purpose is to overcome the shortcomings of existing evaluation methods, which are relatively complex in process. The method obtains standard screen display photon count thresholds Q1′ and Q2′ based on photon counter readings Q1 and Q2. This allows the screen display photon counts q1 and q2 obtained from the corona test to be directly compared with the screen display photon count thresholds, thereby evaluating the stator end corona condition. This avoids the need to recalculate the screen display photon count using a conversion factor before comparing it with the threshold for each corona test, reducing the steps involved in obtaining corona information, simplifying the process, and improving detection and evaluation efficiency.
