Transformer Control Panel Schematics

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.
