Electrical Coordination Studies

What Are Electrical Coordination Studies?

Electrical coordination studies are valuable analyses designed to evaluate the operating time of an overcurrent protective device if a fault occurs in the electrical system. Coordination studies look for areas of miscoordination by analyzing the characteristic curves of fuses and breakers and comparing them against each other. The goal of electrical coordination studies is to protect electrical equipment such as transformers, substations, motor control centers, panel boards, and switchgear.

Why Are Electrical Coordination Studies
Important?

Electrical coordination studies are important to help ensure the safety of the system, the personnel that will be using this system, and the property. When a fault occurs, you expect the closest upstream OCPD (over-current protective device) to open and clear the fault. OCPDs can be selected or adjusted to achieve desired opening time, making the electrical system safe and ensuring system reliability. When coordinated correctly, a singular failure won’t end up causing failure in more of your facility than necessary, which could result in a shutdown or work stoppage. Our goal is to ensure that your equipment operates as designed to keep your people safe and plant up and running.
