Development of shunt passive filter to reduce harmonic on single phase 1.5 kVA isolation tranformer

Abstract

This project is presents a method of using shunt passive filter for harmonic on isolation transformer. Harmonic in power system is defined as current or voltage which defined as multiple integer of system frequency or fundamental frequency. The arise of harmonic current in system is going to further distorted the system voltage that increasingly affect the system performance and give undesirable situation such of them are as failure of control system, mechanical and electrical oscillation in alternator. Since all these above said problems are reserve for the electrical system, so the harmonic mitigation is important for both point of view of utilities and consumers. Harmonic filtering technique using passive filter is the one of the most used and earliest technology present in the system. The 3rd harmonic filter will be used widely because of its contain with high reduce performance and its very simple designing process with low cost factor.
