Harmonic filter improves true power
factor
The HG7 drive-applied harmonic filter not only limits current distortion to less than 7% TDD, it also improves true power factor.
New from TCI, the HG7 is a filter design based on proven technology with significantly improved performance It not only limits current distortion to less than 7% TDD, it also improves true power factor
TDD levels are consistently held low at both full and half loads.
The HG7 contains high quality capacitors rated for harmonic duty.
The capacitors are designed, built, and tested specifically for use in harmonically rich environments.
Installation is simple as the HG7 is shipped ready to install.
It fits easily into motor control centres.
Flexible options allow users to install a filter that fits their application.
TCI's considerable experience with harmonic mitigation technology has led to the development of the HG7, the next generation of the HarmonicGuard Series filters.
Multiple package options will allow TCI customers to choose the right filter configuration for the application.
As every power system is different, harmonic mitigation requirements will differ, and even IEEE limits change based on the system loading characteristics.
The HG7 product returns the power of choice to the customer, allowing for different configurations to achieve different performance and monitoring results.
It is TCI's intention to provide the maximum value to its customers by offering the package and performance necessary for the application.
As power utilities continue to be pushed to the limits of supply capability, rising energy costs and decreasing power quality will continue to be an issue for consumers.
Users continually search for ways to not only reduce energy costs, but also ensure their processes will continue to operate no matter the quality of the incoming power.
To accomplish this, more and more variable frequency drives, UPS systems and other nonlinear loads, are being installed.
For over a decade, TCI has been building harmonic mitigation filters.
From waste water treatment facilities, commercial buildings, and factory floors to harsh mountain environments, reliable TCI filters have been installed to the satisfaction of thousands of customers.
With over a decade of experience in the manufacture and application of harmonic mitigation filters, TCI can provide the right filter for the job.
With so many mitigation techniques available, from multipulse configurations to active harmonic cancellation filters, choosing the right form of harmonic reduction can be a difficult task.
The HG7 is not only guaranteed to perform, its performance matches all but the most expensive mitigation technologies currently available on the market.
The HG7 is easy to install and is shipped with all necessary components including an installation, operation and maintenance manual.
Each unit contains high quality capacitors certified for harmonic rich environments.
It is also important to note that critical applications will continue to operate even if the HG7 shuts down.
In general, the HG7 performs as well as, if not better than, any filter technology currently available on the market today.
Harmonic distortion at the input terminals is typically between 5 and 7% TDD.
With the HG7, voltage drop on the DC bus of a variable frequency drive is less than 2%.
As the filter uses TCI's reactor technology, nuisance tripping is eliminated and drive uptime is dramatically increased.
While attenuating harmonic distortion, the filter also dramatically improves true power factor.
