BARON POWER LTD., a leading resource for Power Quality Products & Services, offers Triplen Harmonic Filter System.
PURPOSE:
Suppression of Third Harmonics in the Network.
APPLICATION:
Single Phase Non-linear Loads that are connected between phase and neutral are generating third harmonic and multiple of it. Being third and ninth harmonic in phase with each other, they arithmetically add up in the Neutral Wire, causing overloading.
SALIENT FEATURES
A special reactor for short-circuiting triplen harmonics.
Reduction of Neutral Current through triplen harmonic suppression.
Installation before any shunting line supplying distorting loads.
Several filters can be connected in parallel.
Wherever Neutral Current is extremely high, Series Reactor along with Shunt Reactors needs to be used. The unit must be sized on the basis of the Line Current and the Neutral Current.If Series Reactors cannot be installed, the filter has to be sized atleast 25% of the distributing Transformer for efficient operation.
Without Series Reactor
With Series Reactor
Benefits:
Negligible 3rd & 9th harmonics upstream of point of coupling.
Several Filter can be installed in parallel for improving the filterability for any increase in distorting loads.
With unbalanced load, a partial re-equalization of the three phases can be obtained by considerably reducing the neutral current
The Rating of the Shunted Reactor is sized based on the MV Distribution Transformer Rating.
