When selecting harmonic filters, Sinotech Group guides customers through a systematic process to ensure optimal performance. First, assess the harmonic environment by identifying the source and magnitude of harmonics, such as non-linear loads like variable frequency drives or transformers. The group's expertise in electrical components and transformer diagnosis helps analyze harmonic spectra using specialized equipment. Next, determine the filter type: passive or active. Passive filters, suitable for fixed harmonic frequencies, are cost-effective and widely used in medium and low voltage distribution systems. Active filters, like dynamic harmonic filters, adapt to changing harmonic profiles, ideal for fluctuating loads in renewable energy or industrial settings. Consider system voltage levels, as Sinotech offers solutions for high-voltage transmission and low-voltage distribution. Evaluate power ratings and compensation requirements to match filter capacity with the system's harmonic distortion levels. The group's partnerships with ABB, Schneider, and Sieyuan Electric ensure access to high-quality filter components. Additionally, factor in installation space and environmental conditions, as filters for outdoor or harsh environments require robust designs. Sinotech provides technical consulting services to assist in selecting filters that comply with international standards like IEEE and IEC. For overseas projects, the company offers comprehensive support, including engineering designs and customs clearance, ensuring filters are integrated seamlessly into power systems. By combining product expertise with professional services, Sinotech helps customers select harmonic filters that enhance power quality, reduce equipment stress, and optimize system efficiency.
