An easy to apply, passive filter capable of reducing Variable Speed Drive (VSD) / Variable Frequency Drive (VFD) harmonics by up to 10 times with none of the inherent problems of conventional filters.

• Treats all major harmonics generated by Variable Speed Drives and other 3-phase rectifier loads (5th, 7th, 11th, 13th, ...)
• Exceeds 18-pulse performance in a smaller footprint, at lower cost and without sacrificing energy efficiency
• Easily applied to input of a single VSD
• No need to phase shift against other VSD's
• No need for costly harmonic studies
• Will meet IEEE 519 standard for both current and voltage distortion
• Input current demand distortion < 8% over entire operating range
• Power factor 0.98 lagging to 0.95 leading over the normal operating range
• Compatible with engine generators since capacitive reactance is < 15% of rated kVA even under light loads

The only passive harmonic filter designed for 3-phase VFD's operating on a 1-phase supply. In remote locations such as farms, golf courses, oil and gas fields and residential areas standard 3-phase Variable Speed Drives are often used as Phase Converters to supply 3-phase motors when only 1-phase power is available. The Lineator 1Q3 is ideal for systems such as water and waste water, pump jacks, irrigation and many others.

The Lineator-1Q3 has been designed to address this application by accepting 1-phase input and supplying a quasi 3-phase supply to the VFD. This will significantly lower both input harmonic current distortion (by up to 10x) and DC ripple current within the VFD. Reducing the ripple current allows for less derating of the VFD which, in many cases, will offset the cost of the Lineator-1Q3.

HARMONY SERIES Isolation Transformers and autotransformers combine very low zero sequence impedance outputs with phase shifting for effective harmonic mitigation. Designed to replace standard or k-rated transformers especially when servicing single phase (120V L-N) non-linear loads, such as personal computers and other power electronic equipment.

EPA Energy Star Compliant Harmonic Mitigating Isolation Transformers with low zero sequence impedance secondary windings. Available with either 0° or 30° phase shift between primary and secondary windings. Configuration of the secondary windings cancels the fluxes generated by the triplen harmonics in the load current thereby minimizing triplen harmonic voltage distortion. Choice of phase shift permits canceling of 5th and 7th current harmonics against those of other loads fed from the same primary supply.

Mirus International Inc. Onics Harmonic Mitigating Remote Panelboard (HMRP)

Up to 4 circuit breaker panelboards with built-in passive harmonic filtering. Eliminates the need for K-rated transformers and double ampacity neutrals. Ideal for broadcasting, telecommunications, data processing, call centers and all office environments with personal computers. Easily installed in either raised or solid floor applications.

Mirus International Inc. Harmonic Mitigating Power Center (HMPC)

The Onics HMPC is an outstanding power distribution unit ideal for the raised floor environment. It incorporates MIRUS' patented and proven Harmonic Mitigating Transformer (HMT) technology. Taking the HARM out of HARMONICS has never been easier.

Neutral Current Eliminator (NCE)

A 3-Phase, Low Zero Sequence Impedance Autotransformer, which when connected near to and in parallel with the harmonic generating non-linear loads (usually connected at the distribution panel), provides an alternate path for 3rd, 9th, & 15th current harmonics (triplens) which the loads create. Patented Field Adjustable Impedance (FAI) feature allows for adjustment of NCE zero sequence impedance to field conditions.

A patented phase shifting autotransformer with a low zero sequence impedance at its output. When connected in series on a 3-phase, 4-wire service to non-linear loads, it provides an alternate path for the triplen harmonics. The CNCE also phase shifts 5th and 7th current harmonics by 180º so that they cancel with 5th and 7th harmonics from other loads on the distribution system. Optional FAI feature allows for removal of triplens from the CNCE input side as well as secondary.

Drive Tamers - Drive Series Transfromers

Designed to replace standard drive isolation transformers, the Drive Tamer is built to not only withstand the harsh harmonic environment produced by Variable Frequency Drives (VFD) but to also induce cancellation of harmonics upstream and thereby reduce voltage distortion throughout the distribution system.

By alternating 0° phase shifting models with 30° models, 5th and 7th harmonics are cancelled upstream. Where 3 loads are being serviced +20° , 0° , -20° models can reduce 5th, 7th, 11th and 13th harmonics, thereby dramatically reducing the voltage distortion these harmonics produce.
