Annotation:
A feature of 10/0,4 kV transformers relay protection is the coordination of the action of time exposures and current settings with the protections of the supply and outgoing elements. The article presents a developed model of digital current protections based on the use of the MatLab Simulink software package with account the coordination with the downstream element.
