why starting current is high and resistance is almost 0 during the starting of motor dc motor...?
1283on 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?
2 2383When a capcitor is used on 440 v thenthis is kvar rating 25kvar .my question is that when we use this capcitor use 480 v &525 volt .how much kvar increase . Plz give my question ans. And give answer with formula .my mail id is rohitashsaini013@gmail.com
