Projects

We offer more than fifteen standard and specialized power system studies to precisely target specific power issues, utilizing a variety of measurement instruments and specialized analysis software packages. Power system studies offer the most focused and systematic approach available to enhance power system performance and identify inefficient system designs, incorrect equipment selection, and potential problems between your equipment and the rest of the power system. Our traditional engineering and analysis offerings include:

Calculates the available short-circuit currents at equipment locations throughout the power system. Evaluation of equipment ratings ensures equipment can withstand, and, where applicable, interrupt an electrical fault. Results are critical for proper system design, including specification and selection of equipment. If the study reveals problems, the study will recommend changes to improve system performance.

Determines the characteristics, ratings, and settings of overcurrent protective devices that will ensure that the minimum unfaulted load is interrupted when the protective devices isolate a fault or overload anywhere in the distribution system. In addition, the devices and settings are selected to provide satisfactory protection against overloads on equipment and interrupt short circuits as rapidly as possible. The coordination study evaluates protective relay characteristics and settings, fuse ratings, and low-voltage circuit breaker ratings, characteristics, and trip settings.

Calculates arc flash hazards associated with energized work at locations throughout the power system in accordance with NFPA 70E, IEEE1584, National Electric Safety Code, and CSA Z462 requirements. Calculations include flash protection boundary and incident energy, with the resulting information being provided on arc flash warning labels to be installed on the distribution system electrical equipment.
