Coordination Study

Fault Isolation - Clearing

A Coordination Study maximizes power system selectivity by isolating faults to the nearest protective device while clearing the fault in the minimum amount of time.

This study can also help to determine and avoid nuisance operations of protective devices due to transformer inrush, motor starting or "race" scenarios where two devices may both end up clearing a fault.

Diversified Technical Solutions  performs the study on all aspects of the distribution system, right from the incoming point from the utility to the panelboard level of your facility.

We provide a full and comprehensive report complete with time current curves (TCC's), single line diagrams, tables of results, settings and recommendations.
