A case Analysis of Internal Discharge of On-load Tap-changer in 220 kV Main Transformer

Graphical Abstract

Abstract

Abstract

A case of on-load tap-changer internal discharge in 220 kV main transformer is analyzed in detail. By analyzing the primary and secondary fault table and disassembly test of the on-load tap-changer, and combining with the operation principle of the on-load tap-changer, the cause of internal discharge is found out accurately.
