Answer / m.ahasanul siam

Yes, transformer losses will be the same for any linear load with the same VA. However, if the load is nonlinear, such as a rectifier, the load waveform will be distorted and the losses will be higher than with an undistorted sinusoidal load current of the same VA.

1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.
