Solutions for the low-insulation problem of 6 kV bus-bar in low-tension side of HV transformer

This article shortly introduces the phenomena and reason of low insulation in 6 kV encapsulate bus bar of general HV transformer in Zhanjiang Power Plant. It brings forward a method to get rid of this failure,that is installing an automatic control invariableness temperature electric heating strap, hence its working principle and installation are introduced. As a matter of fact, the problem of low insulation was successfully solved when the electric heating strap was put into use on site.
