MIRUS Lineator AUHF 3-Phase Passive Harmonic Mitigation Filters

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.

Features

• 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
