Coordination Studies
Analyze protective device settings to ensure proper fault isolation and system reliability.
Service Overview
At Engineering Design Services, our Coordination Study services provide the detailed analysis needed to ensure electrical systems operate safely and efficiently during fault conditions. We take an engineering-driven approach to evaluating breakers, fuses, relays, and other protective devices to ensure they respond properly and selectively when faults occur.
Our team works closely with clients to analyze system configurations, fault current levels, and equipment operating requirements to optimize protective device settings and reduce unnecessary outages. From new facility design to existing system upgrades and compliance reviews, we ensure coordination studies are accurate, practical, and aligned with current industry standards.
By integrating power system analysis, field verification, and operational requirements, we deliver coordination studies that improve system protection, reduce equipment damage, and support long-term electrical reliability.
Whether supporting plant expansions, equipment upgrades, or arc flash mitigation efforts, our team delivers coordination solutions built for safety, performance, and operational continuity.
Engineering Challenge We Solve
Improper protective device coordination can lead to widespread outages, equipment damage, and increased safety risks. Our approach addresses these challenges by:
Improving System Reliability: Ensuring only the affected portion of the system is isolated during faults.
Reducing Downtime: Preventing unnecessary shutdowns caused by improper breaker or fuse operation.
Protecting Equipment: Minimizing damage from short circuits, overloads, and fault events.
Supporting Personnel Safety: Improving protective device response to reduce arc flash exposure.
Maintaining Compliance: Aligning system protection with NEC, IEEE, NFPA, and OSHA requirements.
