In India IS specifications
Normally AC 50 V - 1000V volts are considered LT . 1kV
.1kV to 66 kV is considered HT
and Above 66 kV to 400 kV is EHT ( standard 110 kV ,132 kV ,220 kV , 400kV etc )
and 765 kV is UHT (ultra High voltage and right now in India 1200 kV is in process of testing and it will also come on range of UHT)

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.

In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
