Abstract: Checking and comparing the hardware performance indexes of high-voltage switch cabinet on-line detection equipment, such as linearity error and stability, is the prerequisite for carrying out on-line detection. According to the field application requirements of on-line detection equipment of high-voltage switch cabinet, the least square method is used to optimize the linearity error algorithm. The theoretical and practical results show that the optimized algorithm can improve the accuracy of linearity error calculation, so as to realize the accurate verification and comparison of on-line detection equipment.

Key words: switch cabinet, partial discharge, live detection, linearity error, algorithm optimization
