Brochure
Technical Data Sheet
Typical Specification

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
• Will not resonate with other power system components Will not be overloaded by other line side harmonic sources
• Suppresses overvoltages caused by capacitor switching and other fast changing loads
• Eliminates need for drive isolation transformers, AC line reactors and DC link chokes
• Removal of harmonics improves overall system power factor
• Saves energy by reducing upstream harmonic losses while operating at > 99% efficiency
• Reduces DC bus ripple and increases ride-through capability of the load

'Performance Guarantee'

MIRUS guarantees that the LINEATOR™ AUHF will perform as advertised to reduce harmonic distortion caused by AC Variable Speed Drives and other non-linear loads equipped with 3-phase, 6-pulse, diode bridge rectifiers. A properly selected and installed LINEATOR™ will:

1. Reduce Current Total Harmonic Distortion (ITHD), measured at the LINEATOR™ input terminals at full load, to:
   (i.) < 8% when background voltage distortion is < 5% and voltage imbalance is < 3%
   (ii) < 5% when short circuit ratio (Isc/IL), as defined by IEEE Std 519, is < 20 and when background voltage distortion is < 0.5% and voltage imbalance is < 1%
2. Reduce Current Total Demand Distortion (ITDD), measured at the LINEATOR™ input terminals over its entire operating range, to levels defined in Item 1 above. ITDD is defined as the ratio of ITHD divided by the full load current (peak demand current) of the Lineator™.
3. Minimize the contribution to Voltage Harmonic Distortion of all VSD’s equipped with the LINEATOR™ to < 5% total and < 3% for individual harmonics, as defined by IEEE Std 519-1992.
4. NOT become overloaded by other upstream harmonic sources.
5. NOT resonate with other power system components.
6. NOT have compatibility problems with engine generator sets properly sized for the load.

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™.
