BY82JS/480-30/P7 Series Anti-harmonic Smart Capacitor - 480V 30kvar Industrial Grade with Reactive Power Compensation & Harmonic Filtering

Applications of  BY82JS/480-30/P7 Anti - Harmonic Capacitors

Industrial manufacturing facilities (steel mills, automobile production and heavy machinery)

BY82JS/480-30/P7 series anti-harmonic smart capacitors are ideal for industrial manufacturing environments with high inductive loads, such as steel mills and automotive production lines. In these environments, power capacitors are essential for stable reactive power compensation control and suppression of harmonic interference. In these facilities, non-linear loads such as variable frequency drives (VFDs), arc furnaces, and large motors generate significant harmonic currents, resulting in three-phase imbalance and reduced power factor. By integrating anti-harmonic smart capacitors, the system can dynamically compensate for reactive power, suppress harmonics up to the 25th order, and maintain the power factor above 0.95, ensuring compliance with standards such as GB/T 14549-9315.The capacitor's low-voltage reactive compensation function resolves voltage fluctuations caused by rapid load changes, preventing equipment overheating and minimizing energy losses. For example, in a steel plant, the harmonic distortion of an induction heating system can exceed 30%, which can cause capacitor bank failure. The BY82JS series uses adaptive filtering algorithms and harmonic filtering to eliminate these distortions, reducing total harmonic distortion (THD) to less than 5%810. In addition, its three-phase unbalance correction function evenly redistributes the load between phases, optimizing grid stability and extending the service life of transformers and cables.

Oil and gas infrastructure (pumping stations, refineries and offshore platforms)

In the oil and gas sector, BY82JS/480-30/P7 capacitors excel in harsh environments where low voltage capacitors must withstand extreme temperatures and high harmonic environments. Pumping stations and refineries rely on heavy compressors and drilling equipment that generate harmonic pollution and reactive power shortages. The series offers industrial-grade harmonic mitigation, utilizing advanced DSP control algorithms to detect and cancel harmonic currents in real time (response time less than 5ms).By deploying harmonic-resistant smart capacitors, facilities can reduce risks such as capacitor resonance and overvoltage, which are common in systems with traditional passive filters. For example, in pipeline distribution systems, harmonic amplification of capacitor banks can lead to premature failure. The BY82JS series avoids this through selective harmonic compensation (3rd to 25th) and reactive power optimization. Its low-voltage reactive compensation function also stabilizes voltage levels during sudden load changes, which is essential for offshore platforms where grid reliability is critical.

Commercial and Data Center Power Systems

Data centers and large commercial buildings require ultra-stable power quality to protect sensitive IT equipment. BY82JS/480-30/P7 capacitors solve the three-phase imbalance and harmonic interference problems generated by UPS systems, HVAC equipment and LED lighting, which reduce power efficiency. By deploying anti-harmonic smart capacitors, these facilities have achieved 95% filtering efficiency, thereby reducing neutral line current and preventing transformer overload 110.The capacitor's dynamic reactive power compensation function adjusts to fluctuating IT loads, maintains a power factor close to 1 (above 0.98), and reduces energy costs by up to 30%. For example, in a data center with a power demand of 10 MW, harmonic currents from a server cluster may cause voltage sags. The BY82JS series addresses this issue through instantaneous harmonic filtering and low-voltage capacitor coordination to ensure uninterrupted operation. In addition, its modular design can be seamlessly integrated with existing APF (active power filter) systems, thereby enhancing scalability to meet growing infrastructure needs.
