Pioneer Power Group creates a model of our customers’ electrical distribution systems that contains all sources of fault current (such as the utility grid, generators, and motors) along with all system impedances (such as conductors and transformers).  With this model, we are able to determine the available fault currents at each key equipment location within a power system. 

This information is critical as a piece of equipment subjected to short circuit currents above its ratings could experience catastrophic failures during fault conditions – i.e. if a short were to occur between phases or from a phase to ground.

All short circuit results are presented in tabular form.  An Equipment Evaluation table is also provided that compares the ratings of each piece of equipment to the available fault currents in the distribution system.  If Pioneer determines that any equipment is overdutied, we immediately notify our customers so that cost saving corrective action can be taken sooner in the process of a project.


“Pioneer Power Group came highly recommended to me by a friend at an electrical distributor in PA that I had come to know. From the moment of my first conversation and contact with them, I could tell that this was going to be a special business partnership. The professionalism and help we have received from all of the team members at Pioneer Power Group has been above reproach. The quality of their work and people are exceptional. As a valued business partner, they make us a better business. I would highly recommend Pioneer Power Group to anyone requiring engineering assistance.”
