Abstract: This work presents the minimization of harmonics in 11KV power distribution transformer system using shunt active filter. The aim was to reduce to the lowest percentage the level of harmonic voltage in the Djamija 11kV feeder transformer characterized from the data collected at the Enugu Electricity Distribution Company (EEDC)using k-factor technique which read harmonic percentage of 5.37%. This was reduced by developing a shunt filter using RLC elements and implemented on the 11kV feeder using Matlab. The result showed that harmonic was reduced from 5.37% to 0.085% which according to the Nigerian Electricity regulation Commission (NERC) is within the acceptable tolerance value for harmonics in power system.
Keywords: Harmonic, Filter, 11kV Transformer, Shunt Element, Fourier Frequency Analyzer.
