The HENTG POWER 33kV Automatic Line Voltage Regulator is designed to stabilize voltage in medium-voltage distribution networks affected by long feeders, load fluctuations, and renewable energy integration.

Using an on-load tap-changing autotransformer, the regulator automatically adjusts the output voltage without interrupting the power supply. A typical configuration provides a ±10% regulation range in 32 steps, with approximately 0.625% adjustment per step.

The programmable digital controller supports adjustable target voltage, bandwidth, time delay, line-drop compensation, and forward or reverse power-flow operation.

Challenge: Voltage instability across long distribution feeders

Long feeder distances, changing loads, and renewable energy integration can cause voltage drop, voltage rise, or unstable voltage at remote network points. This may affect equipment performance and overall distribution reliability.

HENTG POWER Solution

The HENTG POWER 33kV Automatic Line Voltage Regulator continuously monitors line voltage and automatically adjusts the tap position under load. With a typical ±10% regulation range in 32 steps, it helps maintain voltage within the specified operating limits. Control parameters and forward or reverse power-flow modes can be configured according to the feeder profile and project requirements.

Utility distribution feeders, rural overhead lines, renewable energy projects, industrial facilities, mining, data centers and distribution substations.
