The differences between traditional capacitors and smart capacitors

• The intelligent capacitor achieves dynamic reactive power compensation through the integration of microprocessors and sensors, supporting real-time monitoring, adaptive switching, and multiple protections against overvoltage, undervoltage, and overheating. In contrast, traditional capacitors rely on external controllers and offer limited functionality.Structurally, the intelligent capacitor features a modular integrated design that combines capacitors, switches, and protection circuits, saving 50% of space compared to traditional solutions and simplifying wiring.In terms of performance, the intelligent capacitor’s zero-crossing switching technology suppresses inrush current to 1.5 times the rated current, and its self-healing film technology provides a lifespan exceeding 100,000 hours, far surpassing the mechanical contacts (with a lifespan of 10,000 to 30,000 operations) and electrolytic media of traditional capacitors.Regarding energy efficiency, the dynamic compensation of the intelligent capacitor reduces line losses by 20% to 30% and supports remote monitoring, which can decrease operational and maintenance costs by 60%. In contrast, traditional capacitors have high static compensation losses and rely on manual maintenance.The intelligent capacitor is suitable for high-demand scenarios such as high-harmonic industrial applications and renewable energy stations, while traditional capacitors are only applicable to simple power grids with stable loads.
• The intelligent capacitors are assembled in a modular fashion within the cabinet, forming an automatic reactive power compensation device. This design breaks away from the traditional structural model of automatic compensation devices and features excellent functions such as zero inrush current during capacitor switching. Additionally, it boasts a simple structure, the ability to accommodate more capacitance within the same cabinet, ease of production, good adjustability of capacity, and convenient operation and maintenance.

BY89S/450 Series Intelligent Capacitors Functions

• Integration of Measurement and Control Technology: The system achieves a perfect combination of measurement and control technology with synchronous switching, controlling the switching speed to eliminate bouncing and enhance lifespan. It tracks and corrects the closing phase angle, allowing the switch to achieve a lifespan of up to one million operations. Compared to existing similar intelligent power capacitors, it offers numerous advantages, including high reliability, low failure rates, low self-consumption, and long lifespan.

• Zero Inrush Current: The system ensures zero inrush current during capacitor voltage application and zero current disconnection, completely avoiding overvoltage during switching. There is no overvoltage breakdown, arcing, or reignition.

• Optimal Compensation: The intelligent capacitor compensates in the most appropriate manner, with comprehensive control functions. It features high-end power quality analysis capabilities, is fully functional, and can be configured with various peripherals to meet different customer needs.

• Comprehensive Measurement and Protection Functions: The intelligent capacitor includes complete measurement and protection features, monitoring internal temperature, grid harmonic content, and providing special protection against phase loss and three-phase imbalance.

• Modular Usage: The intelligent capacitor can be used in a modular fashion, where multiple units automatically designate one as the master and the others as slaves, forming an automatic reactive power control system. In the event of a fault in a slave unit, it can automatically exit without affecting the operation of other units. If the master unit fails, it automatically exits and a new master is generated, forming a new operational system, showcasing a high degree of intelligence.

• User-Friendly Interface: Each individual intelligent capacitor displays its operational status and electrical circuit conditions, providing a simple and intuitive human-machine interface.
