With the development of electronics technology, the loads of power system become more efficient in terms of power consumption but more nonlinear in nature. This nonlinearity nature of loads causes development of harmonic contents in system. The harmonics not only distort the current and voltage waveforms of its own, but also, that of other system connected to it. The use of Isolation transformer is one of the solutions to this problem. This paper discusses about the Isolation Transformer, which is a harmonic mitigation technique. Harmonic contents in any system cause different problems like poor power factor and, hence, it results in lower efficiency of system. The main function of Isolation Transformer is to pass the common mode noise and transverse mode noise to prevent the connected system from above mentioned problems. This paper includes basic principle of working, construction, operation and normal circuit connection of Isolation transformer.
