Working principle
The difference between traditional capacitors and intelligent capacitors
- Modular Structure: Smart capacitors have a modular structure, making them compact, easy to wire on-site, and convenient to maintain. Expanding the reactive power compensation system can be achieved simply by increasing the number of modules.
- High-Quality Capacitors: They use self-healing low-voltage compensation capacitors, which are equipped with built-in temperature sensors to monitor the internal heating of the capacitors, thus providing over-temperature protection.
- Embedded Switching Module: Smart capacitors come with an embedded switching module. This module consists of thyristors, magnetic latching relays, zero-cross triggering circuits, and thyristor protection circuits, enabling “zero switching” of the capacitors, ensuring that the switching process does not cause inrush current or operational overvoltage. The switching module has a fast response time and can be operated frequently.
- Comprehensive Protection Design: Smart capacitors feature functions such as power failure protection, short-circuit protection, voltage phase loss protection, and over-temperature protection, effectively ensuring the safety of the capacitors and extending the lifespan of the equipment.
- Advanced Control Technology: The controlled physical quantity is reactive power, utilizing reactive power flow prediction and delayed multi-point sampling technology to ensure that switching occurs without oscillation. During heavy loads, reactive power is fully compensated.
- Anti-Oscillation Switching Technology: A unique design principle is employed to prevent compensation failure or over-compensation caused by controller malfunctions, thus avoiding oscillation during capacitor switching.
- Automatic Reactive Power Compensation: Smart capacitors automatically switch on and off based on the magnitude of the load’s reactive power, dynamically compensating for reactive power and improving power quality. They can be used individually or in multiple units connected together.
- User-Friendly Interface: The interface displays operating parameters such as current, voltage, and reactive power. It shows the switching status, fault status of the composite switching module, and communication status. It also allows for easy switching between debugging/operational modes and manual/automatic operation functions.

Our Advantages
Condition of operation
When they have been disconnected from the power supply, capacitors require the voltage residuals to be reduced to 10% of their rated voltages before they can operate again. This greatly increases safety, minimizes the risk of electric shocks or damages to equipment, and gives operative safety during maintenance. This also ensures that the wear and tear is much slower, and internal stress and aging are reduced.
Highly intelligent
The product can be used in multiple units in a building block style. When in use, the main unit is automatically generated, and the rest are slave units, forming a reactive power automatic control system. If a single unit fails, the slave unit will automatically exit without affecting the operation of other units. If the main unit fails, it will automatically exit and generate a new main unit to form a new system, which is highly intelligent. The single capacitor displays the product working condition and electrical circuit condition, and the human-computer dialogue is simple and intuitive.
Electrical safety
Compensation is carried out in the most appropriate way, various control functions are perfect, and it has the function of high-end power analyzer, complete functions, good performance, and can also be configured with a variety of peripherals to meet different customer needs.
As with industrialization, smart capacitors are utilized in power systems in a majority of their applications, to optimize system performance and power quality.
Electric Vehicle Charging Stations: During charging, smart capacitors can be used in electric vehicle charging stations to balance loads and cut down on power fluctuations.
Use in Industrial Manufacturing: Smart capacitors are used in large industrial machines and manufacturing lines for power factor compensation, reduction in reactive power, improvement of energy efficiency, and reduction of electricity costs.
Storage Workshop
The capacitor storage workshop is voluminous, thus accommodating a substantial number of capacitors to meet production needs fully. The bright and clean environment does not only create a conducive working atmosphere but also allows proper safe storage conditions for the equipment. The open arrangement leaves enough space between the various equipment, which helps in its ease of operations and management while minimizing accident possibilities. Advanced temperature and humidity control equipment is available for ensuring that the capacitors are stored under best conditions to avoid damage through fluctuations in temperature and humidity. The professionals also carry out regular counting and inspection checks on the equipment so that each capacitor's safety and reliability are guaranteed. These combined factors formulate a capacious, safe and reliable capacitor storage workshop that provides a sound backing for production.
Production workshop
The capacitor production workshop is dedicated to the specialized production of clean and illuminated working conditions pumping an efficient production atmosphere. In this workshop, every detail has been designed and engineered to have a smooth and efficient production process. The assemblers are very experienced, with a wide range of operating skills, and can respond to all kinds of challenges that might occur rapidly during production. Professionalism and teamwork spirit have increased production efficiency rather significantly; thus, every batch of capacitors is produced under very strict quality standards. Such a production workshop is professional and reliable to produce high-quality products and services for customers.
