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

explain all the classes with example
