“…The most common issues caused by harmonics include premature failure of light xtures, premature failure of dc power supplies, heating up of ac motors, even mechanical damage from pulsating torques on motor shafts, interruption evoked into IT cables if not appropriately separated from power cables carrying altered current, noise on telephony systems, and possible data issues [11]. Table 2 shows some effects of voltage and current distortion in a system, whiles Table 3 shows primary consequences of harmonic voltage and current in the power system.…”

Harmonics constitutes multiple integrals of the fundamental frequency found in power systems or electric circuitry systems, are primarily caused by non-linear loads that draw current intermittently or have an impedance that changes each cycle of the AC voltage. This can lead to overheating of the system, loss of original waveform, and damage to equipment or system leading to extra expense economically to the consumer. Since harmonics cause distortion in the system and cannot be eliminated from the system, various methods of mitigating to an acceptable level are introduced, use of filters is one of these methods. An STPF adjusted to the 5th, 7th, 11th, 13th, 17th, and 19th harmonic order was employed in this paper in a power system and analyzed. Data was measured on the point of common coupling (PCC) panel using the power quality analyzer tool, and the system was designed on MATLAB/Simulink environment without the filter applied readings were made, and after the STPF was added, both were compared to the IEE 519-1992 standard for which the STPF totally mitigated the harmonics in the system within the standard required.
