Voltage stabilizers and active harmonic filters enabling reliable power supply of telecom equipment and transmission systems
Telecommunication base station equipment requires exceptionally stable power quality. However, common issues such as overvoltage, undervoltage, surge spikes, and severe grid harmonics frequently affect transmission equipment and transmitter rooms, leading to unstable operation and, in critical cases, network interruptions. These challenges make a static voltage stabilizer an essential component for mobile communication base stations.
Our static voltage stabilizers integrate advanced thyristor switching, microprocessor-controlled AC voltage regulation, and controllable transformers in one system. They deliver high efficiency, fast adjustment speed, and automatic three-phase balance without brush wear or mechanical failure. The units also feature comprehensive protection and alarm functions, including delay start, overvoltage, undervoltage, reverse phase, phase loss, and overcurrent protection, ensuring reliable power for communication facilities.
View MoreLow-voltage power distribution systems in telecom facilities contain multiple harmonic sources such as UPS units, switching power supplies, and variable-frequency air conditioners. These devices generate high levels of harmonic current, with THDi (total harmonic distortion) often exceeding 50%, dominated by 5th, 7th, and 11th harmonics, and sometimes a significant 3rd harmonic component. The high displacement power factor and harmonic distortion seriously degrade system stability and equipment reliability.
Our active harmonic filters (APF) improve communication quality by reducing harmonic distortion, stabilizing distribution performance, and minimizing power losses. By dynamically compensating harmonic currents, the power quality system enhances equipment reliability, extends the service life of communication and power systems, and ensures compliance with modern harmonic environment standards.
