system, harmonic distortion may begin to cause problems throughout the entire system.

Indicators of Harmonic Distortion
^Poor Power Factor
^Transformer and distribution equipment overheating
^Random breaker tripping
^Sensitive equipment failure
^Voltage unbalance

Harmonic Distortion
   before solution
The HG7 not only limits current distortion to less than 7% TDD, it also improves true power factor. Multiple package options result in the right filter configuration for the application.

The addition of a KDR Optimized Drive Reactor will limit the inrush current to the rectifier, rounding the waveform, reducing the peak currents and lowering the harmonic current distortion.

By actively monitoring the load current, the H5 determines the proper current waveform for injection into the system to maintain an acceptable level of harmonic distortion (TDD Reduction to 5% or better at Full Load).

The V1k greatly reduces motor failures on VFD applications by limiting the magnitude of voltage spikes to levels below 1000 volts and slows down the rate of change of PWM switching by a factor of three. The V1k has demonstrated success in protecting the cable and motor insulation by reducing the damaging effects of reflected wave.
Common Mode currents, which can lead to bearing pitting and fluting, are typically reduced by 30%.

Many benefits are obtained from devices that use PWM (Pulse Width Modulated) technology, however the output from these devices are square wave forms. Many applications require a more sinusoidal output, thus ruling out these economical and efficient solutions.
The MotorGuard High Performance Output Filter has been designed to be installed at the output terminals of PWM devices. The KMG filter converts the PWM wave form to a near sinusoidal wave form, allowing sensitive applications to take advantage of the efficiencies and savings that PWM output power supplies offer.

AC Drives rely upon three phase RFI power line filters from TCI, because they provide effective EMC solutions up to 600A. RFI filters are integral components in power systems utilizing drives where high frequency noise should be held to a minimum. RFI Filtering would also benefit any application that utilizes sensitive electronic equipment that may be susceptible to interference, such as radios, computers, control devices, radar, sonar, etc. RFI filters will assist in system CE compliance. Some examples include airports, hospitals, factories with sophisticated automation equipment, pump stations, and commercial buildings.
