Smart capacitor

New Products / New Technology

Smart capacitors are primarily composed of low-voltage power capacitors, integrated with intelligent modules, zero‑current switching components, current sampling units, and other key parts. Leveraging cutting-edge advancements in microelectronic hardware and software, miniature sensor technology, and micro‑network systems, they constitute a standalone, fully integrated smart compensation unit for low-voltage reactive power correction. This replaces conventional modular reactive power compensation devices that consist of an intelligent reactive power controller, fuses (or miniature circuit breakers), and relay‑based composite switches. These smart capacitors offer numerous advantages, including flexible compensation strategies, superior compensation performance, compact size, low power consumption, ease of installation and maintenance, extended service life, robust protection features, and high reliability.

Reactive Power Compensation Controller

New Products / New Technology

The intelligent reactive power compensation controller (dynamic reactive power compensation controller) is built around a high‑performance 32‑bit microcontroller and employs a dual‑core, multitasking operating system powered by a high‑precision metering chip. Its technical parameters are freely configurable, making it suitable for a wide range of applications. It is extensively used for low‑voltage reactive power compensation control. With strong electromagnetic interference immunity and comprehensive protection features, it can measure and display grid line voltage, current, harmonics, active power, reactive power, and power factor, while simultaneously providing real‑time monitoring and protection for capacitor banks. Equipped with a large‑screen LCD and a fully Chinese‑language user interface, it offers functions such as dynamic tuning compensation, harmonic analysis, limit‑exceedance control, event logging, and data upgrading.

Low-voltage shunt capacitor

New Products / New Technology

Low-voltage shunt capacitors are primarily used in power grids for reactive power compensation. They effectively improve the power factor, reduce reactive power losses, enhance voltage quality, and save electrical energy.
