what is the need of representing AC power in sinusoidal waveform? why not in square or rectangular etc...
8 11006We have laid the single core Armoured cable 7 nos ( 2 each phase & 1 neutral ) to cater our electrical load . the issue is though we have Glanded the cable both the end also givan the earthing to the panel both the end we are facing a heavy sparking at the gland side. what could be the reason.
