dielectric strength of vacuum is greater than SF6 but for 132Kv uses sf6 breaker & for 33kV uses vaccum breaker why such a contradiction?
2 4692I have lowered a submersible pump having 100 LPM discharge & 130 Mts. Head, 15 HP rating on borewell. After lowering 108 Meters, It is taking 39 amps & blowing the fuse. Can someone put light what is the cause behind it ?
