What is the effect on in Zone and out zone fault if Phase side CT is Vk/2<30 mA and Neutral side is CT is Vk/4<30 mA for Transformer REF protection
1.what is the difference between ct and cvt? 2.what is the difference between pt and cvt? 3.what is the difference between relays and circuit breakers?
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
