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?
Ceiling fan motor wiring
I have 2 ceiling fans broken. The receiver/control units burned out due to
lightening. One Harbor Breeze and one Hunter's
I took them apart (remove receiver units). Now on both of the motor I see 4
wires coming out from each motor
I really want to know the function of each wire.
Are there anyway I can test to see which is which?
After searching forums I know these 4 wires are from 2 sets of coils inside
the motor, one is Start winding and the other is Runing winding
I could not find the receiver/control unit any where, so I am planing to buy
Capacitors and universal remote controls to make the fans run again.
Anyone has any idea how to do the wiring, please help
WHAT IS MEANT BY OVER EXCITATION IN GENERATOR TRANSFORMERS?
how we can calculate chiller required ampear?
an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly
