in DG synchronization system can i short R,Y,B- phase(DG-1) to R,Y,B Phase (DG-2), HOW IT WORK . WHAY WE NEED TO SYNCHRONIZATION.
1 4182Explain M Var? Which types of problem occurs when reactive power increase at the time of full load of plant and at the time of synchronize of plant?
1773If a rotary UPS is in line through grid power; What would be the impact on Power Factor if the load through rotary ups is 25% , 50% , 75% & 100%. Will the power factor reduce with less load?
1883We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
