what is the need of representing AC power in sinusoidal waveform? why not in square or rectangular etc...
8 8623We 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.
12 12955Is there any reason that we get shock on touching phase wire because the earth is at neutral potential? Is there any reason that the earth is at neutral potential because the neutral is earthed in apower station

what is tri state logic gate
This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
