Abstract :
The authors describe a scheme which provides for the protection of a 11 kV radial distribution feeder, the distribution transformers connected to the feeder, and provides a range of alarm functions and measurements. The relay will also record, cumulatively, interrupted current which may be of use in respect to the maintenance of the associated switchgear
