Can a 50-Hz designed transformer be used at 60-Hz system?
Is the same remains true, when a 60-Hz designed transformer
be used at 50-Hz system? Consider only frequency variation.
The voltage remains as rated value in all cases.
Justify the answer.
Hello, im taking an introduction to PLC..and i'm having a
hard time on creating a program for 2 lamps blinking
alternately with this button characteristics:
1.) One push button (starts upon pressing)
2.) Same push button (when pressed again, will pause the
3.) Same push button (when pressed again, will continue the
4.) Same push button (when pressed within 2 seconds, will
shut off the system)
Pls..i know this is just a simple problem for you guys..
Can a transformer designed for a particular voltage and
frequency rating be used for different set of mentioned
ratings? Assume that the winding does not get burnt because
of overheating at higher voltage.
If yes, then under which constraint it is possible?
i will applied in 1U-1W on 440 volt primary delta side. what is the result
of magtic balance test
whenever any squirrel or a crow falls on the transformer
input line then there is a big explosion and 440 volts of
power is being discharged through the neutral line due to
which appliances in off mode are also burned.we have
earthing for the transformer as well as the bus bar
chamber.why is it happening?
why occ characteristics of generator is also called as
magnatization characteristics ?
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
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
