This coordination study is an essential element of an arc flash study and is intended for engineers, supervisors and relay technicians that are responsible for the protection of industrial power systems. The goal of protective device coordination is to allow for normal equipment operation, ensure circuits open before equipment is damaged and limit outages to the smallest area through selectivity.

These studies are used to verify correct equipment ratings and settings as well as assist in the selection of new equipment. A properly coordinated power system can prevent equipment damage and lost productivity.
