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)
