Answer / tarun aggarwal ymca

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)

Answer / rajiv pandey

Incase of Ac supply LT voltage range is 24 volt to 480 volt
all world & case of DC 6 volt to 650 volt .

Answer / k.prakashchandra

As per I E rules "upto 250 V"

Answer / deepak singh

0 to 1000v low voltage
1000 to 35kv medium voltage
35kv to 220kv high voltage
220 to 720 kv extra high voltage
above 720kv (maily dc supply) ultra high voltage
