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?
