Harmonic filters prevent failure of power instruments and reduce costs
August 14, 2018
Harmonic filters are used to eliminate the harmonic distortion caused by various electrical appliances.
Harmonics are voltages and currents that are constant multiples of the electrical frequency 60 Hz and are generated due to the occurrence of non-linear loads in electrical network. Harmonic filters are used to eliminate the harmonic distortion caused by various electrical appliances such as UPS, inverters, transformers, discharge lamps, arc furnaces, etc. The presence of harmonics in the electrical network can result in malfunctioning equipment through overloading of the neutral conductor, disturbances in the torque of motors, and increase of losses in transformers. Harmonic filtering systems limit voltage fluctuation and improve efficiency and operating conditions, thus optimizing the network.
According to a recent market report, the demand for harmonic filters for eliminating transients from signals and ensuring high power quality is rising. This can prevent failure of power instruments and assist in cost reduction. The filters are widely implemented in capacitor banks used for electrical and heating equipment. Thus, the harmonic filter industry is driven majorly by the rising demand for high power quality and reliability.
Rising demand for electrical equipment in industrial and commercial sectors, along with stringent regulatory standards concerning energy consumption, drives the industry over the forecast period. Furthermore, increasing applications in adjustable speed drives (ASDs), variable speed motor drives (VSDs), light dimmers, fluorescent lamps, and power converters are anticipated to spur the market. Forthcoming enforcement of stringent rules and regulations creates new opportunities for the key players.
However, high cost of harmonic filters, low power factors, and lack of consumer awareness about harmonic suppression may hinder the market growth. Other restraints are offshoring of industry activity limits sales in establishes markets and incorporation of Active Front Ends (AFEs) in VSDs.
The global harmonic filter market is segmented by types, end-users, and voltage level. Based on types, the harmonic filter industry is segmented by active, passive, and hybrid. Active harmonic filters are designed for avoiding non-linear loads and power compensation, and anticipated to hold the largest share. Based on the end-user, the market is segmented by industrial, commercial, and residential. Voltage level segment is further segmented by high voltage, medium voltage, and low voltage. Low voltage filters have application in various harbor cranes, manufacturing industries, and power plants and therefore, lead the global market.
The North American market is expected to be a major contributor due to stringent government policies and high consumer awareness in the region. Latin America and Asia-Pacific are anticipated to have faster growth as the regions see continuous development in power generation and distribution in emerging countries, such as India, Brazil, and China. The market is expected to have expansion in various European countries such as France, Italy, U.K., and Germany over the forecast period.
