Dear sir,
we are getting voltage fluctuations suddenly for 2 or 3
minutes again it becomes normal. we checked each and every
connection some times we are getting 110 volts like that
from earth to neutral again it is reducing we are getting
supply from 45 kva DG set give earthing properly.

generally voltage between neutral and earth occurs when
there is unbalance distribution of load in all three
phases. first check load balancing on phases. also check is
there any single phase heavy load is switched ON at the
time when voltage increases between neutral and earth.

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

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
