The RVR-1 single-phase automatic voltage regulator from China manufacturer Rockwill is a tap-changing autotransformer designed for medium-voltage overhead distribution networks, compliant with IEEE C57.12.It realizes stable line voltage regulation covering a ±10% boost & buck range via 32 fine adjustment steps, each delivering approximately 0.625% voltage correction.
It supports voltage grades from 2400V (60kV BIL) up to 34,500V (200kV BIL), compatible with both 50Hz and 60Hz global power grids. All units are fitted with internal potential winding taps and an external ratio correction transformer, allowing one regulator model to adapt to multiple system voltage levels flexibly.
Two installation configurations are available: Smaller kVA models are equipped with pole-mount support lugs and anchoring fittings for platform/substation installation; large-capacity units come with integrated heavy-duty substation bases for pad-mounted ground deployment.

The RVR-1 pole-mounted automatic step voltage regulators operate on overhead distribution networks to maintain stable line voltage with precise on-load voltage adjustment.
Designed as a tap-changing autotransformer compliant with IEEE C57.12, the RVR-1 Step Voltage Regulator delivers precise voltage correction across a full ±10% boost and buck range in 32 loaded steps, with each step providing approximately 0.625% voltage adjustment.
The RVR-1 Step Voltage Regulator fully complies with IEEE C57.12 standards and operates seamlessly on both 50Hz and 60Hz global power grids, covering system voltage classes from 2,400V (60kV BIL) up to 34,500V (200kV BIL).
All units of the RVR-1 Step Voltage Regulator are equipped with internal potential winding taps and an external ratio correction transformer, enabling a single regulator unit to flexibly adapt to multiple system voltage levels without replacement.
The RVR-1 Step Voltage Regulator provides two field installation configurations: smaller kVA models feature pole-mount support lugs and anchoring fittings for overhead pole or platform installation, while large-capacity units include integrated heavy-duty substation bases for pad-mounted ground deployment.
