Protection Guidelines
(OP)
I am looking for guidelines for protecting distribution systtem networks, especially between 11kV (possibly lower) and 66kV. In particular explicit information on when to use fuses or a combination of fuse and circuit breaker.
Thank you.
Thank you.






RE: Protection Guidelines
The IEEE Red Book, Buff Book and Blackburn's Protective Relaying are all good starting points.

In this system, fuse cannot be used on the primary side of delta-wye incomer transformer because it cannot backup for a ground fault on the secondary side of transformer, because the ground fault at the secondary side of delta-wye transformer is seen as a line to line fault on the primary side.Instead of fuse use circuit breaker on the primary side.
