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.
| Voltage Class | 2.5–19.9 kV typical |
|---|---|
| Frequency | 50 or 60 Hz |
| Regulation Range | Up to ±10% typical |
| Control Steps | 32 steps typical |
| Installation | Pole or platform mounted |
| Insulation | Oil immersed |
Typical configuration only. Final ratings are confirmed against project requirements.
Used on rural feeders, industrial distribution lines, renewable-energy interconnections and networks with seasonal or rapidly changing demand. Control settings and ratings are coordinated with the feeder study.
