Utilities Tech Outlook: Specials Magazine

RHM International eliminates failure points at the high-voltage grid interface, enabling utilities to modernize aging infrastructure without increasing operational exposure. Why are high-voltage grid interfaces increasingly critical for utilities? That capability has become increasingly critical as transmission networks are pushed to deliver greater capacity and reliability under tighter environmental, safety and regulatory constraints. Utilities are expected to extend the service life of assets designed for earlier grid conditions, while maintaining predictable performance across decades-long lifecycles. A persistent source of risk lies at the interface layer. Engineered for traditional grid environments, interface components have historically relied on oil- and SF₆-based insulation. Over time, these media introduce leakage, insulation degradation and maintenance exposure, increasing failure probability and complicating asset management. Growing restrictions on SF₆ under international environmental frameworks further elevate compliance and replacement risk in an already failure-prone category. RHM International re-engineered the interface layer of the high-voltage power grid. The family-owned specialist innovation company replaced oil- and gas-based insulation with a proprietary dry-type medium that operates without pressurization, combustion risk or routine servicing. Developed entirely in-house, the insulation system eliminates explosion risk and fluid-related failure modes while reducing long-term maintenance requirements within existing substations. “When interface assets behave as predictable, long-life infrastructure rather than high-risk failure points, the entire grid becomes easier to manage,” says Eric Euvrard, founder and president. This creates a practical path for utilities to modernize incrementally as they transition toward digitally enabled grid architectures.
