New harmonic filters, MATRIX D series filters, have been introduced by Westek Electronics. The new MTE MATRIX D series harmonic filters cut through obstacles by providing a series of high performance filters that are not only significantly smaller in volumetric size but also have considerable savings in weight through novel magnetic circuit design which in turn helps to reduce their cost.
The new MTE Series D MATRIX harmonic filters will cut heat dissipation in cables, busbars and switchboards--and reduce load on substation transformers as well as provide superior dynamic performance which is of great importance in plant with variably loaded electronic drives.
The use of MATRIX D series filters also find application in dealing with massive line transients such as occurred in the case of 400 kW drives for a series of mine dewatering pumps.
The MTE MATRIX now offers the very latest in harmonic filtering developments: the D series Harmonic Mitigating Reactor with a common core-based filter. The MTE MATRIX D series with its patented unitary magnetic circuit topology represents a significant refinement over the series B while having the same excellent reliability profile.
The advantages of the new MTE MATRIX technology are very significant:
Up to two-thirds of filter space saving
Designed to outperform 18-pulse converter stages for variable speed drive DC-links. The MTE MATRIX D series reduces harmonic content in current to as little as 5%!!
And represents a 40% reduction over the harmonic level from many other commercially available filters
The MTE Series D MATRIX is available as 415 and 690 volt filters with line current rating from 6 amps to 786 amps. Current ratings can be increased by paralleling filters.
