OVERVIEW

ADVANTAGES

• Presents a high impedance to line side harmonics eliminating the possibility of inadvertent importation and overloading capacitor.
• Even under no load conditions, the capacitive reactance (KVAR) of the LINEATOR ™ remains below 15% of its kVA rating ensuring compatibility with engine generators, without the need to switch out capacitors.
• Natural resonance frequency is below that of any predominant harmonic, therefore inadvertent resonance is avoided.
• Reduces current distortion to < 8% and often achieves levels near 5% THID at full load.

FEATURES

• Highly efficient, simple core design
• Treats all major harmonics generated by Variable Speed Drives and other 3-phase rectifier loads (5th, 7th, 11th, 13th …)
• Easily applied to input of a single VSD - no need for costly harmonic studies
• Suitable for application on multiple VSD's provided only VSD's are connected
• 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 or attract line side harmonics
• 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 RF Interference generated by VSD
