Abstract

Harmonics refers to a form of electrical distortion that can adversely impact power systems, electrical equipment, and the overall quality of power supply. The presence of non-linear loads, such as electronic devices, can cause the current waveform to deviate from the ideal sine wave, resulting in higher frequency currents that are multiples of the fundamental frequency. These distortions can lead to several negative effects, such as reduced power factor, increased energy losses, equipment overheating, and electromagnetic interference. These, in turn, can lower system efficiency, increase energy consumption, and escalate equipment maintenance costs. Several approaches have been developed to address the adverse effects of harmonics, such as the use of filters, capacitors, and other reactive components. These techniques aim to minimize harmonic distortion and improve power supply quality. This paper examines the effectiveness of a 1kVAr detuned reactor in mitigating harmonic distortion in power systems and electrical components. The detuned filter reactor reduces the harmonic distortion actively. It does so by monitoring the harmonic content of the power and injecting a counteracting current to cancel out the harmonic frequencies, creating a subtle "detuning" effect that reduces harmonic distortion. Detuned filter reactors find extensive application in radio and audio equipment, among other fields.
