State-of-the-Art Harmonic Cancellation Transformer Sales

Harmonic Cancellation

Thanks to our unique design configuration, even TEMCo standard distribution transformers offer significant advantages over other standard designs. This will be especially evident where there are changes and additions to existing installations affecting the percentage of non-linear component.

In the T-T connected transformers by TEMCo, the triplen harmonics are cancelled in the magnetic circuit and do not flow in the primary windings as in competitive designs. This results in a 14% reduction in copper losses, less heat and extended transformer life.

TEMCo Offers A Variety Of Harmonic Cancellation Solutions

TEMCo offers a variety of harmonic cancellation solutions that may be right for you depending on your power environment.  We can help you find the best solution whether the answer be in phase shifting transformers or a harmonic cancellation motor generator set, or another solution.  Call our power specialists for assistance.

Harmonic Cancellation Overview

In three-phase power distribution the harmonics are the most predominant cause of distortion and heating problems.  These harmonics will cause standard distribution transformers to overheat, burn neutral conductors and naturally fail at the worst possible time.

Harmonic Cancellation – What is Harmonic Distortion

Harmonic distortion is the odd order frequencies of the fundamental 60 Hertz (or 50 Hz, or 400 Hz depending on the intended power frequency).  Nonlinear loads which are so popular now are the main reason we have harmonics.  Nonlinear loads include such things as lighting ballasts, computers, motor drives and controls, communications equipment and other DC-powered loads.  In a three-phase distribution system, the 5th and the 7th harmonics are the most predominant causes of distortion and heating problems.  Harmonics slowly erode the electrical environment causing high maintenance, premature failures and some cases fire.  Harmonic cancellation can be accomplished through a variety of techniques and applications.

Solutions To Achieve Harmonic Cancellation

Harmonic Cancellation with Active Filters and Power Factor Correction Capacitors

An active filter can be used for harmonic cancellation but this can be very expensive and complex.  Active filters digitally create and control reactive power to cancel the harmonics.  Power factor correction capacitors were thought to work to take care of harmonic distortion but can make the matter worse.  Power factor correction capacitors need to be detuned requiring some engineering and a specially adapted custom design.

Harmonic Cancellation With Phase Shifting Transformers

The most economical and easy was to take care of harmonic cancellation is performed with a phase-shifting transformer or what is some times called a harmonic canceling transformer.  These transformers are a new power product to take care of mitigating harmonic problems in electrical distribution systems.  They have built-in electromagnetic technology designed to remove high neutral current and the most harmful harmonics from the 3rd through 21st.  Harmonic cancellation transformers attack the harmonics “head-on” and are clear and easy to understand.  This transformer works on the principal of taking harmonics generated from separate sources, then shifting one source of harmonics 180 degrees with respect to the other and then combining them together.  This results in harmonic cancellation.  Take a sinewave, which contains the 5th and 7th order harmonics with the waveform.  The transformer shifts the 5th harmonic 150 degrees and shifts the 7th harmonic 210 degrees. When the shifted harmonics return back onto the line, the shifted 5th will be approximately 30 degrees away from a perfect 180 degrees with respect to the non-shifted 5th.  The shifted 7th will be 30 degrees from 180 degree with respect to the non-shifted 7th.   This is an excellent blend for these two most corruptive harmonics.  The shifted 5th harmonics are opposite in phase and cancel each other, as do the shifted 7th harmonics.

Harmonic Cancellation Transformers Save Money

In many cases distribution facilities and factories do not address the real problem that causes their transformers to break down.  Replacing a transformer in the middle of production is very costly whether it is in a data processing environment, or factory production, on an assembly line application.  When the failed transformer was in use and needs to be replaced fast there is pressure to find one quickly.  In most cases the first transformer available is the one to get installed.  Efficiency of the replacement transformer cannot be considered.  As a result companies continue to pay extra for wasted electricity year after year.  In most cases the original problem that caused the transformer to fail in the first place has not been addressed …..The Harmonics!

The best solution is to plan ahead and fix the harmonics issues with a harmonic cancellation phase shifting transformer in order to protect the power distribution within your company.  This saves money for the companies who take this wise step in both efficient electrical systems reducing the electric bills and by eliminating the harmonics that can cause transformers and other equipment to fail which would interfere with production.

To take care of your harmonic problem call TEMCo and discuss the best transformer to take care of your power distribution systems.  TEMCo offers a large inventory of harmonic canceling transformers and only offers the highest quality transformers on the market.  TEMCo can ship most transformers within 24 hours and offer service before, during and after the sale.  Find out why so many companies depend on TEMCo for all their transformer and power source needs.
