Active Harmonic Filters are Used Over Passive Filters to Achieve Higher Harmonic Mitigation

Harmonics occur in an electrical power system due to fluctuations in current or voltage levels. Harmonic fluctuations in the power system are a frequent cause of power quality issues and its proliferation severely disrupts the working of the whole system. A harmonic filter is used to mitigate the harmonic distortion created by appliances/equipments that are non-linear load. With growing number of power based electronic equipments, it has become necessary to ensure power quality. The severity of power quality in power networks has necessitated the increasing use of harmonic filters that not only reduce current and voltage harmonics, but also regulates terminal voltage and improves voltage balance in three phase systems.

India Harmonic Filter market was valued at USD 81.1 million in 2012. The market revenue is anticipated to grow at a CAGR of 12.8% from 2013 to 2019. The market is segmented by type into active and passive filters. Among these filter types; passive filters dominated the market, accounting for majority of market revenue share in 2012. However, active filters are expected to grow in the coming years owing to increasing awareness related to the benefits of using active filters over passive filters to achieve higher harmonic mitigation. In addition, another major factor that governs the purchase of harmonic filter is the suitable voltage level. Harmonic filters are available for low voltage, medium voltage and high voltage applications. Low voltage harmonic filters are used majorly in the current scenario. However, the demand for medium and high voltage is expected to increase during the forecast period.

High costs of harmonic filters, lack of awareness, and availability of substitute products are factors that are collectively impeding the growth of this market. In the coming years, the rising demand to safeguard optimum power quality, especially for IT and data center applications, will open growth opportunities for this market. In recent years, government regulations pertaining to quality of power have become strict in India and utility companies are imposing penalties in the instance of non-adherence to the stipulated quality. This is leading to increased adoption of harmonic filters in India.

Harmonic filters find their application across majority of the end use sectors. Some of the major application segments include industrial, IT and data center, automotive and oil & gas industry. Among these applications highest revenue was contributed by the industrial sector in 2012 owing to excessive use of harmonic filters for harmonic correction in drives. Amongst the other application sectors, IT and data center and automotive applications are major applications and these applications are expected to expand their market share in the coming years with an expected increase in the consumer awareness.

Some of the key players for the harmonic filters market in India include ABB India Ltd., Schneider Electric India, Emerson Network Power (India) Pvt. Ltd., Schaffner Group, and Neowatt Power Solutions Co. Pvt. Ltd. among others.
