why we use 230v in single phase and 415v in three phase system.
Thanks @selvamselvamr For making this video.
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.
