Electrical Protection & Coordination

Power system protection aims to protect electrical systems from faults that may occur. This is accomplished by isolating faulty components from the rest of the electrical network, keeping as much of the network stable and operational as possible. Dreiym Engineering PLLC can address your need for a protective device coordination study. Protective device coordination analysis, which analyzes the impacts of short circuits, equipment failure, and other hard faults on a facility’s operation, is also required during Arc Flash studies to remain compliant with safety codes and enforcement agencies. Our electrical engineers stand ready to conduct necessary checks and coordinate your site’s protective devices.


  • AC & DC overcurrent protective device coordination
  • Phase & Ground overcurrent coordination
  • ANSI & IEC coordination & protection standards
  • Client choice on software packages


Correct protective device coordination limits the impact isolated failures can have on your system.  Systems lacking breaker coordination can result in wider facility outages than are required to clear a fault.  When properly coordinated, a single load failure won’t take out more of your facility than is needed to prevent loss or damage from fire.
