Low-voltage automatic voltage regulator

New Products / New Technology

To address the complex voltage issues—such as undervoltage, overvoltage, voltage fluctuations, reactive power deficiency, and three-phase imbalance—caused by long distribution feeders, undersized conductors, load variations, and the integration of distributed photovoltaic systems, Ruitong Electric has developed a series of voltage‑conditioning devices. For challenging voltage‑quality problems at the distribution‑network end, an intelligent, integrated substation‑level regulator can also be deployed. By leveraging energy‑storage units and power‑conversion technology to enable rapid charge–discharge cycles and precise power regulation, this solution effectively mitigates voltage deviations, fluctuations, and imbalances, while delivering multiple benefits—including peak‑shaving and valley‑filling, as well as smoother output from renewable sources—thereby comprehensively enhancing power‑supply quality and grid stability.

Neutral Current Filtering Device

New Products / New Technology

In low-voltage distribution systems, the widespread adoption of power electronic devices such as LED lighting and switch-mode power supplies has increasingly exacerbated the issue of excessive neutral‑line current, with cases even occurring where the neutral current exceeds the phase current. Prolonged overloading of the neutral conductor can lead to elevated cable temperatures and, in severe cases, cable burnout, posing significant safety risks. To address this problem, Ruitong Electric, following extensive analysis and research, has developed and designed the RT‑NLF‑CN series neutral‑current filtering devices.

Dynamic Voltage Restorer

New Products / New Technology

The Dynamic Voltage Restorer (DVR) is a high‑performance compensation device specifically designed to address power quality issues such as voltage sags and brief interruptions in the power supply system. It is widely used in various industrial applications that are sensitive to voltage quality, providing reliable voltage support for variable frequency drives, contactors, PLCs, switching power supplies, and precision control equipment. With millisecond‑level dynamic response, the DVR can inject compensating voltage instantaneously when the grid voltage dips, stabilizing the load side and preventing production disruptions or equipment maloperation.
