I mean to ask not a voltage rating, technical differences and installation procedures , cable types, etc
DIFFERENCE BETWEEN LOW VOLTAGE & MEDIUM VOLTAGE IS AS FOLLOWS
LOW VOLTAGE -3 CORE FOR LV MOTOR LOADS &4 CORE FOR OTHER EQUIPMENTS
MEDIUM VOLTAGE -3 CORE FOR MV MOTOR LOADS & SECONDARY SUB STATIONS
The main difference is in the level of voltage and current, on low voltage we have big current and according to that big losses in cooper, on high voltage we have low current so we usually use high voltage when we want to transfer energy on high distance with low losses, because of this we uses transformer which increase or decrease voltage and current level.
Low Voltage is 1 volt AC Tto 1000V where as Medium Voltage is 1000 upto 44KV
Well, simple definition is:
LV: Systems with voltages less than 11kV
MV: Systems with voltages between 11kV to 52kV
Medium Voltage has Voltage 13.8 KV
Low Voltage has Voltage Range from 220V to 480 V
uptoVlot is considered low voltage generation and or for power distribution
but any voltage from more than volt uptokV is considered to be MV distribution or Transmission of power
Any power transmitted at a voltage higher thankV uptoKV is considered a HV transmission but any voltage above KV to KV used for power transmission is considered as EHV transmission of Power
