Step Voltage Regulator (SVR)

2026/08/20High Voltage Product 230

Overview

The step voltage regulator automatically raises or lowers feeder voltage in small increments as network conditions change. Installed on a pole or platform, it helps distribution operators maintain a more consistent service voltage across long feeders and variable load areas.

Product Advantages

Automatic ControlVoltage sensing and tap control respond to changing feeder conditions.

Fine AdjustmentMultiple regulation steps provide smoother correction than fixed-ratio equipment.

Network FlexibilitySingle-unit and bank arrangements can be selected to suit the feeder design.

Outdoor DutyThe oil-immersed assembly is configured for practical outdoor installation and service.

Typical Specifications

Voltage Class	2.5–19.9 kV typical
Frequency	50 or 60 Hz
Regulation Range	Up to ±10% typical
Control Steps	32 steps typical
