He is an Electrical Engineer with over 16 years of experience in roles spanning from design engineer to lead engineer in power generation, renewables, and oil & gas facilities. His areas of specialty include power distribution, relay coordination, power system studies, motor controls, and electric heat tracing. Ravi has been involved in several large projects from conceptual definition through commissioning and start-up.



    Turbine Injection Skid

    ONEC provided design and construction services for a water injection skid to supply de-ionized water to the NOx skid at the client’s power plant. Working from the client’s conceptual design, ONEC undertook a detailed design of an integrated storage/production/recirculation system to maintain the high purity of de-ionized water during storage.  The water injection skid was fabricated at ONEC’s panel shop in Edmonton.

    Involvement: Electrical Engineering, Mechanical Engineering, Fabrication


    Mine 480V Services

    ONEC worked with a client to supply 480 V main service entrances for their mine near Wabamun, Alberta. The project also included the installation of 300 kVA and 150 kVA transformers, including the provision of engineered drawings.
