Harmonics Mitigation

MIRUS International Inc. designs and develops world class power quality improvement products for mission critical operations. Our specialized product line includes highly efficient harmonic filters, transformers, autotransformers and Data Center power distribution equipment. Mirus’ solutions minimize disruption to the power supply, improve reliability and adhere to the strictest of regulatory requirements while also saving energy and reducing operating costs.

Since 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).

Our 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.

We 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 Partners.

With 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.

Our 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.

At 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.
