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 possible1075

in HT service 3ph 4 wire service Y-phase voltage shows zero . whether it is meter fault? or what be the reason ? if y-ph voltage zero ,can current is recorded? reasons for failure?
Actually I have a doubt on neutral and earth.we use Ac power without taking neutral by connecting to earth,but at that time does it affects on efficiency of any electrical components or no? If yes how?
we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
IF I KNOW THE AREA OF CROSS SECTION OFTHE WIRE , WATTAGE OF THE LOAD ,VOLTAGE SUPPLY WHAT IM GIVING TO THE LOAD AND ALSO POWER FACTOR OF LOAD ....... SO GIVE ME FOR WHAT AMOUNT OF CURRENT I SHOULD USE WHICH TYPE OF CABLE?
