1.0 General Information
1.1 General
Lineators™ are manufactured to provide optimum
performance for a lifetime of uninterrupted service.
Careful attention to the following instructions is
recommended for safe and reliable operation.
Installation, operation and maintenance of
Lineators™ should be performed by authorized
persons, familiar with electrical apparatus and the
potential hazards involved.
As with any electrical device, Lineators™ must be
installed according to the requirements of the
national and local electrical codes.
2.0 Product Description and
Application
2.1 Description
The Lineator™ is a purely passive device
consisting of a revolutionary new inductor
combined with a relatively small capacitor bank.
Its innovative design achieves cancellation of all
the major harmonic currents generated by VSD’s
and other similar 3-ph, 6-pulse rectifier loads
(resulting in THID of < 8% and often as low as
5%). Although referred to as a filter, the
Lineator™ exhibits none of the problems that
plague conventional filters.
2.2 Harmonics from other Sources
The Lineator™ will present a high impedance to
line side harmonics, thus eliminating the possibility
of attracting harmonics from upstream non-linear
loads.
2.3 System Resonance
The natural resonance frequency of the Lineator™
is below that of any predominant harmonic,
therefore inadvertent resonance is avoided.
2.4 Leading Power Factor
The leading PF of the Lineator™ at light loads
consists of very low capacitive reactance <15% of
rated kVA for units larger than 75HP. In the
majority of applications, switching out capacitors
under no load conditions is not necessary when
using the Lineator™.
2.5 Harmonic Distortion Reduction
The Lineator™ will reduce current distortion to <
8% and typically achieves near 5% THID when
operating near full load.
2.6 Isolation Transformers
The high let-through impedance of the Lineator™
will provide many of the same benefits as the drive
isolation transformer, while also dramatically
reducing the harmonics injected into the power
system by the drive. It accomplishes this in a
much smaller footprint, so when there is no need
for voltage transformation, the use of the
Lineator™ eliminates the need for a drive isolation
transformer. And when voltage transformation is
required, the isolation transformer will not require a
K-factor rating.
WARNING
Danger! There is the potential of
electric shock whenever working
in or around electrical equipment
such as the Lineator™. Power
must be shut off before any work
is conducted on a Lineator™.
