HYTBBW Series Pole-Mounted High Voltage Reactive Power Compensation Device
The HYTBBW pole-mounted high-voltage reactive power compensation device provides localized shunt compensation on outdoor distribution lines. Fixed, line-compensation or automatically switched configurations can be selected according to voltage level, feeder load and required capacity, helping improve power factor, reduce line current and losses, and support voltage quality along long rural or industrial feeders.
