Step Voltage Regulator (SVR)

High Voltage Product 220

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.

Pole-mounted step voltage regulator
