Abstract- This paper, development of experimental kit on variable speed drive typed harmonic current passive filter for undergraduate study was proposed. The proposed kit was consisted of experimental kit and laboratory sheets and it was designed for using as experimental study on harmonic current filtering method by passive filter that designed for installed variable speed drive (VSD). T connected Inductor – Capacitor –Inductor (LCL) Filter was selected and designed to set as experimental kit based on experimental objective, and function analysis. With and without filter for VSD conditions were set up in the proposed kit. Two laboratory sheets were designed following kit objectives. Circuit experimentation of 1 kilowatts of VSD typed passive filter were applied to verify the proposed kit. As results, input current behaviors of filter installed system were clearly following theory, implying the proposed kit can make understanding for undergraduate students.
