PCE also has extensive experience in preparing coordination and sectionalizing studies. Coordination studies are completed using SKM Power Tools and ETAP.  A complete model can be built for the system being modeled. This allows evaluation of equipment ratings based on the fault study and protection coordination. When modifications are required based on analysis, PCE is able to provide appropriate recommendations. For transmission systems, we use Aspen One Liner and ETAP which allows not only overcurrent coordination, but also line distance protection analysis.
