Enhancing Single-Phase Transformer Performance with A Pass-Tune Filter Under Various Load Conditions

Although single-phase transformers are crucial parts of contemporary electrical power networks, reactive power demands and harmonic distortions can severely impair their performance under non-linear. In order to improve transformer performance by reducing harmonic distortions and enhancing power quality, this study suggests integrating a pass-tune filter. The study shows how the suggested filter affects transformer efficiency and voltage control under a range of load conditions, such as linear, non-linear, and fluctuating loads. A single-phase transformer (3 KVA, 220 volts, and 50 Hz) is simulated in this work. Different topologies of filters have been used in this work. The results demonstrate the pass-tune filter's potential as an affordable remedy for power quality problems, guaranteeing dependable transformer operation in practical applications. Different loads (linear load and non-linear load) before and after adding the filters were examined. THD due to higher distortion in the R-L load reaches 22% and 49% for the voltage and current, respectively. Fast Fourier Transform (FFT) analysis after applying the filters to both voltage and current shows acceptable total harmonic distortion values within standards (less than 5%). Simulation findings show that the pass-tune filter effectively reduces losses, improves overall operating stability, and lowers total harmonic distortion (THD).
