An Active Harmonic Filter is an electronic power inverter using IGBT semiconductors with various control loops to increase Power Factor and reduce harmonics by injecting a dynamic cancellation signal into the power line. Thereby reducing amperage, KVA, KVAR, circulating currents, harmonic resonance, line voltage imbalance and closed delta-winding losses. The Active Harmonic Filter solution from Power Correction Systems improves the efficiency and operation of AC Motor Systems, AC Variable Frequency Drive (VFD) Systems and works well with virtually every Electrical and Electronic Device in your facility. Conforms to IEEE 519-1996 and IEC 1000-2-2.
Who
needs the Active Harmonic Filter Solution? You
do, if you are operating with today’s sophisticated automation using VFDs DC
Drives, SCRs, Process Controllers, computer-based Robotics, rectifier-based
equipment or any other non-linear loads in commercial or industrial application.
Any facility, from the oldest to the newest, which incorporates
non-linear process controls and VFDs In its operation, is a potential
beneficiary of an Active Harmonic Filter solution. You
also need this solution, if you would like to reduce the costs of your
electrical operation of your facility. In
the past, efficiency was increased by installing and using standard capacitors
on power lines. However, with the
implementation of modern sophisticated automation, the increase in the amount of
switching supplies and rectifier circuits now being used in manufacturing has
caused efficiency to decrease. These switching supplies and rectifier circuits create
harmonics that can overheat capacitors. Industry
engineers and consultants agree that the application of standard capacitors to
these systems is NOT always possible or feasible, and in some cases detrimental
to the electrical systems. A
detrimental system resonance can occur and cause 100% over-voltage conditions
when there are harmonics circulating.
Power
Correction Systems
offers advanced solutions to the problems of harmonics, Power Factor and voltage
imbalance, the Active Harmonic Filter series provides economic savings and
enhanced systems reliability due to Power Quality. Installation of the Active Harmonic Filter is quick and easy,
requiring no mechanical break to the power lines.
