why we use 230v in single phase and 415v in three phase system.

This video explains about the Indian Electrical Voltage standards and also answer the below mentioned questions. 1. Why we use 3 phase system. 2. why we use 415V in 3 phase system. 3.why we use 230v in single phase system. 4. why we use square root 3 in electrical calculation. 5. Different btn line and phase voltage. 6. Indian secondary distribution system voltage.

What is the voltage level of LT and HT line

full form of LT and HT

 LT - Low tension ( Low voltage )

• voltage range - Below 1000 Voltage
• Used in secondary distribution system

HT - High Tension ( High Voltage )

Voltage range - 1000 V to 33 kv

Used in primary distribution system

EHT - Extra High Tension ( Extra High Voltage )

Voltage range - Above 33 kV

Used in transmission system
