ACTIVE HARMONIC FILTER

BARON POWER LTD., a leading resource for Power Quality Products & Services, offers Active Harmonic Filter System.

PURPOSE

Suppression of Harmonic Levels in Electrical Installation.

SALIENT FEATURES
	Instantaneous response to the dynamic variation produced by harmonic load.
	Easy Expandability using other modules in parallel.
	Various order of Harmonic Compensation.
	Reduction of Current Harmonics.
	Immunity from harmonics in the network.
	No risk of harmonic resonance.
	No risk of overloading.
	Significant reduction in the voltage waveform distortion.
	Reduction in voltage drop on transformers and cables.
	Reduction in Temperature rise on Transformers and Cables

APPLICATION
	Network with THD Harmonics above the limits.
	Network with various Order of Harmonics.
	Low Reactive Power.

PRINCIPLE
	Active filter installed in parallel to the harmonic generators, analyses the harmonic current produced by the non-linear loads.
	Current transformer measures the current being drawn momentarily by the load.
	Control unit in the harmonic filter analyses this current for amplitude and harmonics.
	Feeds a current into the supply system whose amplitude and individual harmonic numbers is exactly equal to the current drawn by the load but which is 180° out of phase with it. This is done not by absorbing currents, but by injecting additional currents whenever required.
	Harmonic currents cancel each other out and the supply network only has to supply the fundamental frequency and is not contaminated with harmonics at the point of connection.

BENEFITS
	Reduction of Voltage and Current Waveform Distortion.
	Reduction of Voltage Drop on Transformers and Cables.
	Any additional demand due to extension of the installation can be met at any time by adding further modular Blocks.
