Harmonics & It’s Mitigation

Higher harmonics - an increasing problem which affects all power distribution network in industrial, commercial, telecommunication and medical application. Most of power converting equipment or facilities can generate harmonic current.

Axpert-i-Sine, the Multi Functional Active Harmonic Filter is designed with intelligent control algorithm, dynamically changes the switching frequency to optimized the performance & efficiency. The performance of Axpert-i-Sine AHF is least affected by supply voltage harmonic distortion. It provides selective harmonic attenuation up to 51st order.

Customer Voice

We would like to put on record our sincere appreciation to AMTECH ELECTRONICS (INDIA) LIMITED, Gandhinagar, Gujarat, who has been awarded work for harmonic mitigation at our plant located at Pipan, Sanand Taluka of Ahmedabad. For this prestigious project, AMTECH has supplied 200 Amp, 3-Phase, 3-Wire, 415 Volt ACTIVE HARMONIC FILTER (AHF) in June 2020. AHF is performing upto the satisfactory mark since installed. Not only these harmonic filters have mitigated the harmonics, but have also reduced failures (due to harmonics), thus improving the overall reliability of the system. Also, AMTECH team has given us necessary support as and when required. We wish them good luck and best wishes for all their projects.

We would like to put on record our sincere appreciation to Amtech Electronics (India) Ltd., Gandhinagar, Gujarat who has been awarded work for harmonic mitigation at our plant in Gulbarga, Karnataka. Amtech has supplied 100A, 3-Phase, 3-Wire, 415V AHF (02 Nos.) in 2019 to mitigate harmonics in the system. After installing the same harmonic distortion brought down to the limit specified by IEEE-519 Standard, thus improving the overall reliability and efficiency of the system. AHF is working satisfactory since its installation. Amtech is giving us excellent support as and when required. We wish them good luck and best wishes for all their business.


This is certifying that AMTECH ELECTRONICS (INDIA) LIMITED, GANDHINAGAR has supplied 150 A, 3-Wire Active Harmonic Filter. The above system is performing up to the satisfactory mark since installed. After installation of these AMTECH makes Active Harmonic Filters the harmonics are very much under the limit as per IEEE 519 — 1992 and IEEE 519 - 2014 guidelines. AMTECH has been giving us necessary support as an when required.


Frequently asked questions

What is Harmonics?

Harmonics are sinusoidal voltages or currents having frequencies that are integer multiples of the frequency at which the supply system is designed to operate (termed the fundamental frequency; usually 50 or 60 Hz). Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines.

Is there any Guideline/Standard available for Harmonics?

IEEE Standard 519-2014 provides guidelines for harmonic current and voltage distortion levels on distribution and transmission circuits.
