Dear Eleceng01
The line is radial and there is a parallel line. One of the end is a generation and i don't have information about the other end.
Thanks
We are developing a protection requirement to a power line of 69kV. This line is about 7 kilometer. Because of costs we use 50/51 protection and 67N to backup protection. Is this scheme efficient??? What are the disadvantages of it?
Thanks
Ed
