1991, Mirus International Inc. has been a supplier of specialized power
quality products to reduce or eliminate harmonic problems and save energy
in electrical power distribution systems worldwide. As true innovators,
our unique approach to harmonic mitigation has produced many patented
designs useful in addressing the problems associated with harmonic generating
non-linear loads such as personal computers, telecom equipment, broadcasting
equipment and Variable Frequency Drives (VFD).
strength is in our technical expertise as problem solvers. Principals
at the company have been successfully resolving difficult power quality
problems for decades. This includes the first application of a zero sequence
harmonic filter for the removal of heavy 3rd harmonic current in a high
tech manufacturing facility in 1986. Our Neutral Current Eliminator, or
NCE, is a refined version of this first device.
are the original inventors of Harmonic Mitigating Transformers which combine
low zero phase sequence impedance with phase shifting to treat harmonics
generated by non-linear loads. This strategy not only improves power quality
by reducing voltage distortion and flat-topping but also saves energy
by lowering the harmonic losses within the transformer and upstream distribution
system. We actively promote the financial and environmental benefits of
our highly efficient transformer products and are proud to be Energy Star
Partners, US Green Building Council members and Rebuild America Business
the introduction of our revolutionary LINEATOR Universal Harmonic Filter
(UHF) in 1999, we have begun to capture a significant portion of the market
for premium harmonic Variable Frequency Drive solutions. Our newest generation
Advanced Universal Harmonic Filter (AUHF) has built on this success and
now is the solution of choice for many of the major VFD manufacturers
and is being specified by many consulting engineers worldwide.
one-of-a-kind Harmonics & Energy (H&E) Lab offers the ability to fully test products under ‘real world’
non-linear load conditions. Through performance validation in the H&E
Lab, our customers can be assured that our promised power quality improvement
and cost saving energy reductions can be fully realized.
Mirus, we are motivated by the challenge of finding solutions for the
most difficult of power quality problems and to design the highest efficiency
transformer and harmonic filtering products on the market. In this way
we expect to continue our steady growth, one satisfied customer at a time.
