power factor I.e the value of cosine angle between voltage and current .it is 0,6(or less) to 0.9(max 0.99) but it is not fix as 0.8 that is why transformer is rated.

A dc motor running on dc drive whose input is 3ph AC what will happen if we change the phase sequence of dc drive for e.g (R Y B) is connect as R B Y, will the motor run as same as previously running before changing phase without any effect

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
