Active Harmonic Filter

True Harmonics Solution

Active Harmonic Filter.

High harmonics escalate complications which affect all power distribution networks in industrial, commercial, telecom and medical applications.

Most of the power converting equipments or facilities can generate harmonic current. Axpert-i-Sine Series Multi-Functional Active Harmonic Filters are designed with intelligent control algorithm which dynamically adjust the switching frequency to optimize the performance and efficiency.

The performance of Axpert-i-Sine Series AHF is less affected by supply voltage harmonic distortion and it provides selective harmonic attenuation up to 51 st order.

Amtech offers both 3-phase, 3-wire as well as 3-phase, 4-wire Active Harmonic Filter, Static Harmonic Filter. Whenever there are single phase non-linear loads like computers, there is an accumulation of triplen harmonic current in neutral. Our 3-phase, 4-wire Active Harmonic Filters are the best choice for such applications.

  • Range : 60…600 A, above this connect in parallel
  • Voltage Range : 230 V, 415 V, 480 V, 600 V, 3-Phase, 3-Wire & 4-Wire, 50/60 Hz

Frequently Asked Questions

Harmonics are sinusoidal voltages or currents having frequency 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 frequency are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines.

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

Harmonics in power systems are primarily caused by non-linear loads, which draw current in a manner that is not proportional to the voltage applied. This results in distortion of the voltage and current waveforms, generating harmonic frequency that are integer multiple of the fundamental frequency. This is the source of most harmonic distortion in a power system.

The nonlinear loads like, Variable Frequency Drives, Induction Furnaces, Saturable Reactors, Electronics Ballast, UPS, Thyristoried Power Control Devices, Switch Mode Power Supplies, Computers, Single Phase Rectifiers, AC Regulators and Cyclo-converters to name a few.

Yes, the adverse effects of harmonics are, Frequent capacitor failures, Nuisance tripping of Circuit Breakers, Electronics card failures, Motor overheating, Power loss in cables, Higher power loss in transformers, Transformer de-rating, Nuisance fuse blowing, Misfiring of Thyristor/static devices, Voltage flickering and many more.

To name a few, Passive Filters, Active Filters and Hybrid Filters (combination of Active and Passive Filter) of suitable rating and design can be employed to control the harmonics. However, any solution should be installed only after thorough study of system, otherwise it may lead to rise of problems.

The limit of allowable voltage and current harmonic distortions are set by standards like IEEE, IEC, EN etc.
