Reliability assessment of transformer reliability in Benin City, Edo State and environ


Eyenubo Ogheneakpobo Jonathan, Okpare Anthony Onoharigho, Ebisine Ezekiel Ebimene

A good understanding of system reliability is to enable system planners to seek better ways of improving the system network for better performance of transformers in a typical secondary distribution system having any type configuration whether radial or ring. In this work analytical technique was used in combination of the electrical transient analyzer software for the simulation of transformers used in these eight (Koko, Nekpenekpe, Ikpoba Dam, Etete, Guinness, G. R. A., Street I, Street II) feeders’ stations from four numbers of transformers 132/33/11kV of 3 x 60 MVA and 1 x 30 MVA in Benin City, Edo State. The results of the analysis revealed that Koko Feeder Station is the most reliable in the network when compared to the other seven feeder stations from analysis of the system indices. An expected sensitivity analysis interrupting cost (ECOST) of any type of cessation that occurs has been included.
