Abstract

In this paper

based on the structure

operation condition and on-site monitoring video of the capacitor bank

the explosion accident of the 35kV shunt capacitor bank is analyzed and summarized through diagnostic test

theoretical deduction and video image analysis.The experience is summarized for how to assure safe and stable operation of the capacitor bank in the future

how to find out in advance the existed defect with advanced live detection technology and prevent the accident.The preventive measures on the influence of grid harmonic generation as well as the safe operation of capacitor bank are proposed

so to void reoccurrence of the similar accident.
