With today’s rapidly changing technologies and electrical environments, many "side effects" are created. Harmonics are one of the most potentially troublesome and unpredictable problems affecting the smooth operation of today’s modern facilities. Harmonics is a term used to describe distortion in an electrical distribution system and can be applied to both voltage and current. How to Find Out if Your Business is Affected by Harmonics: There are a number of steps that can be taken to confirm the presence of harmonics in the electrical system:
Measuring Harmonics In order to develop an engineered solution to this problem, it is necessary to measure the harmonics with a Harmonics Analyzer. This is the unit we at NRG, Inc. utilize in our Harmonics Testing Service. This instrument provides detailed information on the spectrum of harmonic currents and voltages including:
This type of testing should be performed by an experienced person familiar with the use of the type of equipment. The results of the testing is what is used to determine the best possible solution to the problem. The accuracy of the test results are critical to the success of the project. As with any mitigation technique, a detailed system study must be undertaken in order to predict a result. Moreover, the misapplication of any device intended to correct any electrical problem can have serious safety implications. There is, in fact, no "off-the-shelf" solution to harmonic problems. Northeast Resource Group, Inc. is an experienced team of power quality experts. Advanced software as well as advanced testing equipment provided by NRG Inc. is used to analyze the power system at all frequencies to optimize the application of various types of harmonic mitigation devices.
