Typical power circuit configuration involves 3 phase diode
rectifier at the input to convert the AC input to DC
voltage, LC or C filter to reduce the ripple in the DC
voltage. 3 phase IGBT inverter stage converts this DC
voltage into variable voltage variable frequency output as
per the desired pattern.

why there is no short circuit when any resistance is used between phase and neutral?

I have carried out wiring for lighting in a shed in Industrial area which contains Metal halide lamps & have balanced in 3ph.Now when we put all the lines on in the daytime the current taken at 3phases at MCB comes to be equal i.e.28,29,28Amps respectively but in the night time i.e between 7p.m.to 11p.m. at the same MCb the current is 52,59,62Amp, though I have fit 63A MCB it is tripping in the above period.What may be the reason.? Note: This industry is located in industrial area where majority of steel ingot manufacturing plants are there. Whether this may be due to harmonic? what should I do to overcome above problem.pl suggest urgently.
