A Harmonic Filter is the solution to today’s disruptive power anomalies. These harmonic anomalies are quite common with the increased utilization of electronics on power distribution systems and the use of more non linear loads. Devices that are major contributors to harmonics include the following: computers and peripherals, fluorescent lamps, welding machines, DC power systems and chargers, uninterruptible power supplies, AC/DC variable speed drives, and frequency converters.
Harmonics themselves are actually multiples of fundamental frequency. For instance, in a 60Hz system, the 5th harmonic would be 5x that frequency. The term "total harmonic distortion" defines the total amount of harmonics found in a power system.
The problem with the presence of harmonics in a power system is that they create what’s known as “dirty power,” or poor power quality. The undesirable affect of “dirty power” is higher RMS voltages and currents. RMS voltages can lead to a myriad of problems like blown fuses, failed power factor correction capacitors, and tripped breakers. The most damaging of all RMS problems is the additional heat it can generate, which can reduce the life of an electrical device by as much as 50 percent.
A Harmonic Filter and be employed to negate these unwanted effects. When power factor correction is necessary, a Harmonic Filter can step up to solve power quality issues. A Harmonic Filter must be carefully designed to avoid unexpected interactions within an electrical system. TEMCo is your answer to a carefully designed Harmonic Filter. Their team of harmonic filter specialists will work directly with you to ensure you have the proper Harmonic Filter to meet the needs of your power source situation.
Types of Harmonic Filters
There are basically three types of harmonic filters which are the fixed passive Harmonic Filter, switched passive Harmonic Filter, and active Harmonic Filter. We will explore each in greater detail as follows:
- Fixed passive harmonic filters are best utilized when considerable harmonic distortion exists and precise power factor correction is required. By connecting the tuning reactor with the capacitor cells, dangerous resonance situations are avoided. The fixed capacitor banks are tuned to the 4.7th harmonic, reducing dangerous levels of the 5th harmonic.
- Switched passive harmonic filters are much like the fixed passive harmonic filter detailed above. However, the switched passive harmonic filter employs a solid state controller which will add or subtract capacitance as loads change. This process ensures the desired power factor is at a consistent, maintained, level.
- Active harmonic filters provide harmonic control that is “active.” This type of harmonic filter begins by monitoring distortions in the electrical signals, determining the magnitude and frequency of harmonic anomalies, and then canceling the offending harmonics with opposing current.
Highest Quality Harmonic Filters
If you are dealing with disruptive power anomalies brought about by harmonics, TEMCo has the correct harmonic filter to handle harmonic cancellation with ease. Whether you need a fixed passive, switched passive, or active harmonic filter, TEMCo has a huge selection of all three, from the top manufacturers in the industry. TEMCo can also custom design and build a harmonic filter to your exact specifications.
