Description
Dear All,
Welcome to the course of understanding schematics of "Transformer Protection Panel Schematics". This course covers complete schematics of 20/26MVA 132/11 kV transformer protection 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.
This training is designed over as schematics, that will also be available to download.
