Description
Dear All,Welcome to the course of understanding schematics of "Transformer Control Panel Schematics". This course covers complete schematics of 132 kV transformer control panel. Trainer have over 18 years of field experience and has worked at 11/132/220/500kV Substation, 1263MW power plant, 660kV HVDC system. worked with several companies, SIEMENS, ABB, GE, SEC, KE, WAPDA, NTDC, ARAMCO, SABIC, MARAFIQ. Trainer has given hundreds of trainings online and offline, so it will be great to join this training and take advantage of field experience. In this training, we have selected the schematics of 20/26MVA power transformer. This is a control panel that is installed at the control room at remote location. This training is designed over as schematics, that will also be available to download.Following topics are covered in this training:Learn Single line diagram of transformer feederGeneral arrangement of the panel, explained how the panel is designedMaster different symbols used in the schematicsAC Supply distribution Heating and lighting circuitAC loopDC distributionDC loopDC & AC supply supervision circuitAC supply fail circuitDC supply fail circuitControl and alarm supplies in panelDC supply changeover schemeOpen & closing circuit of Circuit BreakerOpen and closing circuit of line isolator, busbar isolator, earth switch, VT linkRemote position indication schematicsDiscrepancy switch & how it operatsFlicker relay circuitContact multiplication circuitAnnunciation circuitMetering circuitSupervision lampsGeneral arrangements side and rear views.Thanks
