why the transformer secondary voltage is more than the load
end voltage like t/f 11KV/433V for 415V(terminal voltage)

Answer Posted / a.k.sen

To compensate the V-drop in the Transformer (considering Impedence value)at full load, Secondary voltage at 433V is selected for load terminal voltage at 415V.

We 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

1)we have 1000 cfm Blower,Dia-1Mtr,Velocity of air 94 m/s 2)We have Natural Air velocity 94m/s 3If i Put Wind Mill in natural air ,speed is 94m/s Then it will generate Assume 100kw 4)If i put same wind mill across the Blower,air speed is same 94m/s now the Question is Will it generate 100 kw?
