Abstract

Emergency Unit Section is a busbar panel for distributing power to the essential equipment unit 380/220V, such as Turbine Lube Oil, Jacking Oil Pump, and Turning Gear. The Emergency Unit Section is supplied from the Emergency Diesel Generator (EDG) and PC unit Section, both units Auxiliary Transformer (UAT) and Start-Up Standby Transformer (SST). In condition of normal operation, Emergency Unit Section is supplied from PC Unit Section (UAT), while the Emergency Diesel Generator (EDG) operates when the unit is disturbance (blackout). In condition a supply PC Unit Section (UAT) experienced a loss of power, the EDG will automatically direct back-up supply power to the Emergency Unit Section, until the supply power PC Unit Section (SST) supplies busbar panel Emergency Unit Section. However, the power supply transfer from EDG to Unit PC Section is less reliable, due to the power loss at the Emergency Unit Section in some time. At the Emergency Unit Section it is necessary for a synchronization between EDG and PC Unit Section, so that the continuity of the power at the Emergency Unit Section can be awakened and the operator does not need to start equipment Emergency Unit Section again.INTISARI: Unit Emergency Section adalah suatu panel busbar yang digunakan untuk menyalurkan daya guna keperluan peralatan penting unit 380/220V, seperti Turbine Lube Oil, Jacking Oil Pump, dan Turning Gear.
