The Challenge: Elevating Below-Grade Transmission Grounding Efficiency
A prominent utility company faced a critical challenge in optimizing below-grade transmission grounding systems for a 230kV connection between a nuclear power plant and local substation. This high voltage line was pulled through and spliced across 26 underground concrete vaults and required multiple reliable grounding solutions for each.
With unique challenges that included standing water, confined spaces, and safety concerns such as sparking due to welding, the alternative solutions fell short in meeting stringent industry safety standards, leading the client to seek out DMC Power for a robust, customized approach.
