Harmonics in an electrical system/equipment occur due to fluctuations in the current or voltage. The propagation of harmonic frequencies is one of the most important cause of power quality problem in the electrical systems. Harmonic causes torque fluctuations, misfiring in variable speed drives and heating in the system. Thus, in order to ensure optimum power quality, complete suppression of harmonics is a critical consideration. The growing need for ensuring power quality coupled with increasing use of non-linear loads such as variable frequency drives producing harmonics is expected to drive the demand of harmonic filter in the coming years.
Passive harmonic filters that are built from a combination of power components including inductors, resistors, and capacitors are tuned for a particular frequency of interest. Over the last few decades, passive harmonic filters have been finding use in a wide range of applications due to their superior compensation of the reactive power, simple and robust construction, and relatively lower cost as compared to other harmonic filters. Their preliminary utilization in power factor correction applications has been the driving force for their extended use within power networks. Passive filters are required to be applied only after considering their effect on the whole network. Incorrect application of harmonic filters may lead to early failure of the filter. However, the passive harmonic filter when designed and applied correctly, offers a cost effective solution to harmonic distortions at all voltage levels.
For the purpose of providing and in-depth and detailed analysis of the market, the global passive harmonic filter market has been segmented into product type, voltage level and end user. Different types of passive harmonic filter available in the market includes tuned passive harmonic filters and detuned passive harmonic filters. In addition, depending on voltage level at which harmonic filter is to be applied, the market has been classified into low voltage, medium voltage and high voltage. Moreover, data related to the demand of passive harmonic filter across various application in different end user segments including industrial, IT (Information Technology) and data centers, automotive, oil and gas and water treatment industry among others, is also provided in this report. Furthermore, information related to current market situation along with expected demand trend of passive harmonic filter across different regions such as North America, Asia Pacific, Europe, Middle-East and Africa (MEA) and Latin America.
Increasing adoption of variable frequency drives (VFDs) is one of the most important factor anticipated to promote the uptake of harmonic filters during the forecast period from 2017 to 2025. Rise in automation across different industrial and commercial applications and growing demand for electrical efficiency has increased the demand for Variable Frequency Drives (VFD). The fluctuating voltage levels in variable frequency drives results in the generation of harmonic and this harmonic keeps on multiplying until it is filtered from the electrical system. This in turn is expected to trigger the demand of harmonic filters in the coming years. Increasing demand for passive filters can be attributed to their superior harmonic elimination capabilities and improved stability.
Among the different types of passive harmonic filter available in the market, detuned passive harmonic filter held the largest market share in 2016 and is expected to maintain its dominating position in the coming years. Reduced maintenance cost, stabilization of voltage supply, improvement in overall power quality and savings in electricity bills through reduced kWh losses and elimination of reactive power are some of the most important attributes anticipated to boost the adoption rate of detuned passive harmonic filter across various end user segments.
On the other hand, demand for passive harmonic filter form industrial sector generated the highest revenue in 2016 and is anticipated to witness a stable growth during the forecast period.
Geographically, the global passive harmonic filter market is anticipated to be majorly driven by Asia Pacific region both in terms of growth and market share in the coming eight years. Poor quality power in the region has resulted in increasing losses during distribution and transmission, violating energy efficiency norms set by state and federal regulations. This has put pressure on the utilities in the region to ensure improved power quality, resulting in greater demand for harmonic filters.
Some of the major players operating the global passive harmonic filter market includes ABB Ltd. (Switzerland), Schneider Electric SA (France) and Emerson Power Network (The U.S) among others.
