how the direction of rotation in a dc shunt motor could be reversed?2 2633
in the exciter the power is feeded from battry or control or whatever.and we need it in the generators for the stating . do we need it in the shutdown also?i mean the exciter>2 2595
What is proximeter? where it is used and why?1 2746
why protection meter is always connect to star1 1871
Can we use same copper cable for both AC & DC power.3 3560
why the earth pin is thicker than other pins in a plug? If it is for reducing resistance, then why the copper earth wire is not so thick as earth pin of socket?
how do we fix the rating of mcb required for a specific capacity of the electric motor2 4072
if there is nutral in phase why we use earthing wire and grounding? even at fault condition the fault current flows to neutral (it is a lower path)1 2380
