if you are asked to charge a m/c urgently, you can go for dummy charging using 3-phase load through a, say 16A MCB, and if the MCB does't trips then there is no problem you can go for permanent charging.

in our all power plant have connected in grid and grid voltage and plant voltage is same, but as per as electrical concept the power will transmit from high potential to low potential but here altough same,then how power transmit from power plant to grid.
