We are having a 2000KVA DG set. It trips with Over speed
and Engne Hot when the mahine is stopped in full speed. How
shall I analyse the block load and reverse power.Is the
problem related to power factor. The machine which runs on
this DG is having all Synchronous motors with incividual
Drives.
Throw -off at full load results in high speed before the
governor controls the speed and also overheating

In secondary transmission i.e., in distribution side, supply for homes are connected through different phases in order to balance the 3 phase load. But in practical we saw nearby house doesn't have power due to single phasing. But other two phases give supply. How it's possible? it doesn't make "single phasing"?
it is difficult to interrupt a capacitive current because (a)it has a leading power factor (b)current magnitude is very small (c)the restriking voltage can be high (d)stored energy in the capacitor is high
