• INTRODUCTION:-

On the pleasant day of 5th October, 2012, a great visit arranged by respected H.O.D. Prof. R.A.Patel under great supervision of Prof. V.B.Patel and Prof. D.K.Shah for the students of 3rd Sem Electrical of UVPCE. This report is based on that visit. On that day great technical knowledge is fed to students by respected staff of Kherva substation specially Jigar soni sir (junior engineer).

Mr.soni has explained control room in detailed as per technical side with reference to line diagram.He permit us to visit the Battery Room which is the heart of the substation.He also share his knowledge regarding switch yard.At the end of the day,visit was succesful as mr.soni leads us to increase our vision towards substation.
