Final Year (7th Term) Session 2010-2014LAB#1 FamiliarizationObjective: To familiarize with the layout and functions of units forming the 70-002.Procedure: The 70-002 units will already have been assembled into a powerframe frames. The 60-132 power supply unit will already have been connected to 70-220 rear panel and the mains three phase supply by the cables provided.The measuring instruments are grouped in top left of the frame, the load units are in the top right, the 70-220 firing and bridge circuits are in the center and the power supply and storage bin are in the bottom.
