Dynamic Power Quality Technology for modern infrastructure

Dynamic and complex load profiles, there are more challenges faced by the network and energy users to provide high power quality.

Active Filters

Active Harmonic filters are systems employing power electronics. They are installed either in series or in parallel with the nonlinear load to provide the harmonic currents required by nonlinear load and thereby avoid distortion on the power system.

Sizing Active Harmonic Filter from Power Analyser Data

The Graph below shows Harmonic Current Distortion in the form of %THDi. This is hovering between 20 and 25%. Ideally, it should be less than 10% and preferably less than 8% THDi.

What are active harmonic filters?

Active harmonic filters are parallel filters (which means the current doesn’t go through the filter) that are used to reduce, or mitigate, harmonics to tolerable levels as defined by IEEE-519.

Different compensation capacitor banks

The reactive power supplied by the bank is constant irrespective of the variations of the power factor and load of the receivers.

Active Harmoni filter Applications

Many industrial facilities place poor power quality at the top of the list of inefficiency factors responsible for losses due to reduced productivity and lower quality of products.
