This paper deals with design and simulation of a three-phase shunt hybrid power filter consisting of a pair of 5th and 7th selective harmonic elimination passive power filters connected in series with a conventional active power filter with reduced kVA rating. The objective is to enhance the power quality in a distribution network feeding variety of non-linear, time-varying and unbalanced loads. The...
Transformer fault diagnostic methods based on dissolved gas analysis (DGA) using artificial neural network (ANN), fuzzy logic & a self-adaptive neuro-fuzzy inference system (ANFIS) has been presented in this paper. Firstly, a fuzzy system development technique is proposed, in which the rule base is derived from IEEE and IEC DGA standards. The second step of the work deals with the application...
