Adjustable speed drives (ASD) are used widely in process industries due to better speed regulation, quick response and reduced wear and tear as compared with mechanical alternatives. However, based on topology of ASDs, harmonics injects in the power system and causes distortion of voltage and current waveform and creates some harmful effect to the system. Hence, mitigation techniques are required to limit injection of harmonics in the system. One of the mitigation techniques is the application of passive filter. Installation of passive filter at input of ASDs, reduces harmonics, regulates voltage in steady and dynamic conditions, improves power factor. However, passive filter accompanies problems such as creating resonance to the network which needs to be calculated in harmonic study and resolved during filter sizing. This paper involves procedures for sizing and comparison of different passive filters.
