Switchgear and Protection are the two vital terminology of Electrical power system. Normally thecomponents of any switchgear needs better protection schemes to be set for a composite power system. Manyexplorers worked on artificial intelligent breaker but an indulgence of fuzzy theory is nevertheless very absentin case of buchholz relay. Here in this paper discussion has been drawn in favor of the Artificial IntelligentBuchholz (AIB) relay where inputs are level of transformer oil and rate of oil rising due to over current. To fitwith the transformer tank it is needed to measure level of transformer oil and the rate at which volumeincreasing. The constructional feature of a rate of rise pressure relay is taken into account in this work alongwith the working principle of a buchholz relay. The change in the inputs will give a crisp output to change thecontacts state from normally closed to normally open by tripping via alarm circuit indeed like the basicbuchholz relay does. The entire concept has been developed under MATLAB environment using Mamdanibased Fuzzy Inference System. Experimental output data validates the implementation of TransformerProtection by Using Fuzzy Logic Based Artificial Intelligent Buchholz Relay.
