Protective Device Coordination Studies

A Coordination Study maximizes power system selectivity by isolating faults to the nearest protective device, as well as helping to avoid nuisance operations that are due to transformer inrush or motor starting operations.

The objective of Protective Device Coordination Study is two folds. The first is to provide the optimum protective and coordination performances from protective devices time current characteristics curves. The second is ensure that the protective device settings do not violate the NEC requirements for conductors, transformers, motors and any electrical equipment.

The Protective Device Coordination Study is a prerequisite to the Arc-Flash study.
