Nexus Selected as Supplier of Choice for Generating Company’s Fleet-wide Arc Flash Assessment

A bright blue arc flash moving across a generator panelNexus has been selected to work with one of America’s premier power generating companies which operates more than 75 generating stations, with nearly 26,000 megawatts of capacity, in 16 states and Canada. Nexus Engineering Group has been identified as their supplier of choice to perform arc flash and coordination studies at its plants in accordance with plant operating standards, which are based on IEEE 1584-2018. With a growing and evolving fleet of generating systems, it is necessary to keep the electrical distribution systems documentation up to date and the protection schemes in place.

With a diverse portfolio of generating stations, including geothermal and natural gas, Nexus has been asked to analyze arc flash incident energies and boundaries of the auxiliary equipment and communicate the information to plant personnel via reports and arc flash labels. Nexus has also been tasked with performing protection coordination reviews of the electrical protective devices in order to minimize electrical outages when faults occur.

Nexus will participate in other engineering support efforts such as substation upgrades, lightning protection reviews, specification and electrical safety program reviews, analyzing tripping situations, adding plant load, motor starting and assisting with the design for the modification of the auxiliary electrical system.

Engineers from Nexus will visit each site and work with the plant personnel to validate their electrical system models, run calculations and develop a punch list of information required. Once punch list items have been implemented, Nexus will develop setting changes where high incident energy can be reduced, provide proper label guidance, update models and issue a final report.
