Lineator AUHF

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
