Study on state evaluation of high voltage switchgear based on sudden-change component of fuzzy clustering algorithm

Fuzzy clustering algorithm is proposed for a high voltage switchgear state evaluation, In order to make the evaluation results have comparability, the algorithm uses invariant center for clustering method, and it can directly cluster samples without prior information. The data of live detection using sudden-change component in order to reduce the disturbance to the surrounding electromagnetic environment was accepted. The feasibility and effectiveness of the algorithm was verified by real data in transformer substation.
