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. 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. 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 new 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.
