Reactive Compensation
GDR
GDR automatic low-voltage capacitor bank for power factor correction in LV networks.
Product Overview
GDR low-voltage reactive power compensation cabinets improve power factor and reduce reactive power demand in LV distribution networks. The automatic capacitor bank switches steps according to measured power factor and load conditions, helping industrial and commercial customers reduce energy penalties and improve voltage quality.
We supply fixed and automatic compensation configurations with controller, switching device, protection and optional harmonic filtering. The cabinet can be supplied as a standalone unit or integrated with LV switchgear.
Each cabinet is factory assembled and tested before shipment. We provide drawings, test reports, export packaging and commissioning support for overseas projects. The final assembly is checked against the approved drawing before packing.
Before production, our engineers review the project single line diagram, protection scheme, metering requirements, cable entry and local grid standard. After approval, we complete factory assembly, routine testing, export packaging and documentation, and provide commissioning and after-sales support after delivery.
