why we use single core 630mm2 cable for transformer secondary side
how does a liquid starter reduce the starting currents?
when ac current flows thru d coil of a contactr,it energizes,magnetic field attracts d contact of the coil...nw wont dt ac current in d contct induce current back on to d coil thru mutual inductance leading to high currnt in d coil
How Load Factor, Demand Factor, Diversity Factor etc best applied in designing an electrical circuit? Is it allowed to consider these factors in each and every panel in an electrical distribution system? Can any body suggest a good book for reference?
