Harmonics refer to the shape or features of a voltage or current waveform compared to its fundamental frequency. In power systems, the ideal scenario involves smooth sinusoidal waves without any harmonics. However, when waveforms deviate from this ideal sinusoidal shape, they introduce harmonics. These harmonics have the potential to distort the voltage waveform and cause various issues within the power system. A power system’s ability to perform at optimal levels is compromised when harmonic distortion enters the system. It creates inefficiencies in equipment operations due to the increased need for power consumption. The increase of overall current required creates higher installation and utility costs, heating, and decreasing profitability. Power system problems that can occur without a harmonic filter: • Increased installation and utility cost • Overheating of components • Equipment malfunction • Nuisance tripping of circuit breakers • Inaccurate measurements on sensors • Telecommunication interference What are Harmonics?
