Active power is that power which is used for useful work
and reative power is used for producing magnetic flux for
rotating electrical machines.Explanation by simple example:-
if we want to go from Delhi to Mumbai by plane. If plane is
flying at 3 kms height (vertical height) it is reactive
power and horizontal distance(from Delhi to Mumbai)it is
called active power or useful power.

Answer / indranil banerjee

Reactive power is that component of power for which we
don't pay any money, but we put our own system to a
pressure.

It is like somebody climbing upstairs and coming down
without doing anything.

what do you mean by 600VA for UPS

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
