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. Content List General Characteristics Component List Single Line Diagram Legends Under Voltage / Over Voltage Relay F27 Concept of in comer and outgoing feeders Use to bus tie breaker Need of DC supply / batteries for at substation for control and protection What is disadvantage of using AC supply for control and protection Protection philosophy, tripping and closing coil function Interlocking of Incomer 1 & 2 & Bus Tie explained UVT Under Voltage Trip Coil in Air circuit breaker r circuit Trip / Close Coil Save contact Interlock Logic, Auto Manual Off operations Symbols & Legends DC Supply Distribution SLD Drawings Aux Contacts use, NO & NC DC Supply Distribution detail Drawings Metering & Indication Circuit at Control Panel DC Annunciator Circuit Socket & Lighting Circuit Typical Lamp Test Scheme Teal Strip Drawings Front and Side View Best Regards
