Product Description
HENTG POWER 33kV Automatic Line Voltage Regulator
Product Overview

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.

Key Features
  • Rated system voltage up to 33kV
  • Automatic on-load voltage regulation
  • Typical ±10% regulation range
  • 32-step precise voltage adjustment
  • Forward and reverse power-flow control
  • Programmable digital controller
  • Optional monitoring and SCADA communication
  • Pole-mounted, pad-mounted, or substation-type designs
  • Customized insulation and environmental configurations
Typical Applications
  • Utility distribution feeders
  • Solar and wind power networks
  • Rural and remote distribution systems
  • Industrial and mining facilities
  • Long-distance power distribution lines
  • Substations with frequent voltage variation

HENTG POWER provides customized 33kV voltage regulator solutions based on system voltage, load current, feeder conditions, insulation level, installation environment, and communication requirements.

Key Project Challenge and HENTG POWER Solution

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.

Typical Applications

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