Every time you make a significant change to your electrical distribution system—an expansion, reconfiguration, additional load or upgrade—you challenge its reliability. Emerson’s power system studies can help you manage the increasing complexities of maintaining a safe, reliable and efficient electrical distribution system.
The Short Circuit / Coordination Study can reduce the risk your company faces and help avoid catastrophic losses. The study will determine the magnitude of currents flowing throughout the power system at various time intervals after a fault occurs and evaluates the size and settings of a system’s protective devices, such as relays, fuses and circuit breakers, and the circuits they protect.
The goal is to provide power transformers, switchgear, substations, motor control centers, panelboards and other electrical equipment with the required protection. The study also assists with selecting appropriate types, ampere ratings and device settings to ensure minimum service interruption under overload and short circuit conditions and to ensure the protective device closest to the overload or short-circuit condition is the one that operates in order to isolate the failure as quickly as possible.
