power quality evaluation is highly essential for modern power system to maintain proper accuracy for responsive equipment. There are various power quality indices which evaluates the power quality but it is highly crucial for combining all the indices into a single value which can evaluates the power quality successfully. Considering representative quality factor(RQPF), detailed pollution factor(DPF),total harmonic distortion(THD) and short circuit level(SCL)an untraditional power quality index can be evaluated. Fuzzy inference system has been implemented for doing the incorporation of different power quality indices. In this paper THD module is formed by the union of total harmonic distortion voltage(THDV) and total harmonic distortion current(THDI ) and THDSCL module is formed by the fusion of THD and SCL. The innovative THDSCL has better significance for measuring power quality Index
