Switzerland, Zurich: Hitachi Energy has launched the Compact Line Voltage Regulator (C-LVR) at CIRED 2025, introducing a transformer-integrated solution aimed at addressing voltage stability challenges in modern distribution grids.
Designed to meet the evolving needs of utilities and industries, the C-LVR combines voltage regulation and power transformation in a compact format that fits within the footprint of a standard distribution transformer. This eliminates the need for additional infrastructure or space while enabling active voltage control at the feeder level.
As electricity networks shift from centralised, unidirectional power flow to more complex and volatile conditions due to distributed energy resources (DERs) and electrification, grid-edge voltage management is increasingly critical.
“The C-LVR enables smarter, more resilient distribution grids,” said Adrian Timbus, Head of Portfolio & Market Strategy at Hitachi Energy. “It helps utilities manage voltage stability amid the growing integration of renewables, electric vehicles, and digital infrastructure.”
The C-LVR is SCADA-compatible, suitable for compact secondary substations, and prepared for retrofit or new installations. It automatically compensates for voltage fluctuations, supporting grid modernization without major redesigns.
This launch expands Hitachi Energy’s voltage control portfolio, which now spans from tap-changing transformers at the node level to feeder-level C-LVRs, and line-end regulators.
