Transition

As networks connect more solar, EVs and electrification load, voltage becomes a front line operational challenge. Fundamentals helps utilities keep voltages within acceptable limits across the whole system, from primary substations through to the low-voltage edge.

Their Total Voltage Control approach brings together proven products, engineering services, and specialist support so network teams can modernise voltage control without waiting for major reinforcement programs.

Fundamentals delivers an ecosystem for end-to-end voltage compliance across HV, MV and LV networks. Offering substation AVC and tapchanger expertise to LV regulation, so utilities can stabilise voltages, protect customers, and connect more low carbon technologies.

At the substation level, Fundamentals provides automatic voltage control and tapchanger management designed for modern operating conditions, including fluctuating power factors and distributed energy resources. This helps maintain voltage headroom and reduce the operational friction that comes with volatile power flows. Fundamentals also supports utilities with control scheme services, including scheme design, settings design, installation, testing and commissioning.

For asset-heavy networks, their tapchanger services help extend the life and performance of legacy equipment with spares, repairs, troubleshooting and refurbishment capability. That helps reduce unplanned risk and keep critical assets available while transition plans mature. On the low-voltage network, Fundamentals solutions address voltage rise and imbalance driven by high rooftop solar and changing customer demand. LV regulation can reduce voltage variation and support compliance at the meter
