Effects of Increased Frequency on Output Voltage from a Step-Down Transformer

[yousuf21]

Hi everyone,
I have a query in my mind that what will happen when frequency of main voltage(220 V ac) increases from 50 to 60(or more) accidentally.What will be effect on output voltage(and frequency) from a step-down transformer connected next to main supply cable for power supply circuit?

Plz please answer my question

It's a good question. What do you think might happen? and why?

If I had some idea than why should have I ask here? Seriously I'm confused

Use a step-down transformer only if one side of the 220 mains is a good safe ground, and if the 220 ac plug is polarized.

Examine the effect of the frequency change on the transformer output voltage, input inductance, reactive input current, excitation B field, and core losses.

The generator set will have an AVR (automatic voltage regulator) this operates independently of the frequency so should maintain the voltage at the correct level.

I'm thinking the situation is probably of an electrical appliance designed for 50Hz mains that OP is tempted to try operating off 60Hz mains.
