Description
Dear All,
DC Distribution Panel (DCDB), are the one of the important panel in substation / power plant / factory etc. DCDB explained in this training has two incomers (two sources). One supply is feed through Battery Bank – No:01 and other is feed through Battery Bank- No:02. Interlocking is provided between incomers and coupler, we have explained single line diagram, interlock logic, interlocking schematic / wiring functionality is explained, what is normal position of any equipment, normally open and closed concept is also explained. Finally you can find schematics drawing for self-study.
Following topics are covered.
