If in a 3 phase supply if the load current is 200A what
value of current the each phase R,Y & B will carry?
Answer Posted / sudhakar.g
The three phases will carry equal current and also the netural will take part 1/4 of phase current
If u saw any project site the main LT panel ACB breaker that will show how much each phase will carry and netural how much its carrying also....
In my site the 3200A breaker the R phase 900A , Y phase 715A, B phase 720A and Neutrsl it is carrying 179A ...It will vary also...
Hope you understand this....
If u have any queries pls mail me sudhakar28485@gmail.com
