Can I use 240V /1 phase / 50Hz electrical equipment in 240V / 1 phase / 60Hz power source? Kindly provide some technical explanation.

It might work it might not it depends on the application.
For some things, yes.
For things that are not frequency sensitive like incandescent lamps and electric heaters (without blower motors) there generally isn't a problem.
Most electronic power supplies are designed to be compatible with most of the World's voltages - the rating are usually printed on them.
Many 50Hz single phase transformers will work on 60Hz but the reverse doesn't hold true as a general rule.

You might also use Search and the Advanced Search here, with some
combinations of 50Hz vs 60Hz, 50 verses 60, 60 verse 50, etc.
There will be a lot of threads available for your reading pleasure! :smile:

As others have indcated, the real technical answer here is "It Depends".
Please give a little more info on the equipment.

I a product that is an 1nductor is design for 60hz such as a motor or a transformer, it is designed specifically for use with 60hz. As you may recall the alternating current magnetizes the cores reversing the magnetic field with the change in direction of the current. The design of the core is optimized with both 60hz and the voltage.
If one were to decrease the frequency the current will increase to a point where the core goes into magnetic saturation. When the core goes into magnetic saturation a transformer will cease to be a transformer, the primary current will skyrocket and the secondary voltage will crash. Motor likewise will cease to be motors when the stator laminates saturate and can no longer induce their magnetic field into the rotor laminates.
However a transformer of motor design for 50 is with almost all certainty capable of being applied at 60hz with no problem except the synchronous speed of the motor would be based upon 60 and it will run faster.
Core saturation can also happed should there be an over voltage. It is not uncommon for most devices to be able to function at up to a 10% over voltage.

A transformer or motor generally cannot be run at 50Hz if 60Hz rated unless the voltage is reduced. Volts/Hertz must be held constant. Similarly, 50Hz equipment can be run at 60Hz but the capacity will be less. If you have a motor, use a VFD to make sure the motor voltage and frequency match its rating. The 50Hz input to a VFD is not a problem since the drive converts it to DC anyway. Just watch out for current ratings.

Yes, a 60HZ transformer could be applied a 50 HZ if the voltage were to be reduced but to what point in order to prevenet core saturation?? Then, if one identified such a voltage the transformer output voltage most likely would be useless.
Also, I may have missed something but I wasn't aware that this was a variable frequency application but the simple application of a 60hz rated motor on 50hz which is considered from a different perspective.
