Short Circuit Coordination Study

Maintaining System Reliability

A Short Circuit Coordination Study is crucial to maintaining system reliability and identifying potential risks associated with short circuits and the overall performance of your power systems.

When designing a new electrical system or upgrading an existing one, a Short Circuit Coordination Study is vital to ensure that the protective devices (such as circuit breakers, fuses, and relays) are correctly selected and coordinated with your power system. This means that in the event of a fault, the device closest to the fault will operate first, minimizing the impact on the rest of the system.

For existing systems, a routine study may be performed as part of routine maintenance or system evaluation. It is especially important for our engineers to review and analyze data to determine whether there have been changes to the system that might impact overall performance or utility upgrades.

Post-Fault Analysis

Global Power Supply conducts a Short Circuit Coordination Study using Electrical Transient Analyzer Program (ETAP) software, to create a replica model of your system, and simulate various short circuit scenarios, allowing us to observe how your system’s protective devices respond to unexpected events.

Based on the results from our ETAP program, our expert engineers will provide you with our recommendation for the most reliable device as well as the settings in order to optimize and improve coordination of your power system’s protective devices.

We offer comprehensive training sessions and support on short circuit safety, and we ensure your team has proper understanding of short circuit coordination studies, and the resources needed to maintain a safe and efficient working environment.

“We learned first-hand about the importance of a short circuit study after an incident at a processing facility for our winery. We had a problem when a mis-sized circuit breaker failed to trip and allowed a spike of in rush current to reach our processing equipment, which destroyed a conveyor motor and caused us a two-day shut down to replace damaged equipment. This could have been avoided with properly sized circuit breakers. To make sure it never happened again, we had a professional analysis of our electrical systems and a short circuit study performed.”
