Abstract

In electrical power systems, the periodic and steady state disturbances of thecurrent and voltage in wave form are called harmonics. Due to the symmetrical structure of the sinusoidal wave in power systems, single harmonic components such as 3, 5 and 7 are formed. The presence of harmonic current and voltage in the electrical powersystem causes the sinusoidal wave to be disturbed. The harmonic currents flowing from the mains generate negative effects on the devices connected to the grid and impair the quality of the energy. Especially with the harmonics they produce, the loads thatdisrupt the energy quality; Switchable power supplies are lighting elements, transformers, generators, converters and arc furnaces operating in accordance with the principle of gas discharge. Adverse effects caused by harmonics; overloading of the compensation systems, overheating of the transformers, decreasing of the voltage values and consequently increasing the losses, deterioration of the insulation levels of the devices and the malfunction of microprocessors can be listed. One of the effective methods used to eliminate the effects of harmonics is to use a harmonic filter
