on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf  has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
