## What Happen if DC Voltage is Apply to Transformer Input?

Considering the importance we can say a transformer is the most efficient electrical machine ever invented on the earth.

The main function of the transformer to step up or step down the voltage to the desired voltage level keeping the power level same at both primary and secondary or in simple input power and output power is equal.

So, we can define as a transformer is a static device which converts electrical power from one circuit to another without changing its frequency and it Steps up or Steps down the level of AC Voltage and Current.

Finally, we draw the working principle of transformer that works on the principle of mutual induction of two coils or Faraday Law’s Of Electromagnetic induction.

When the current in the primary coil of the transformer has changed the flux linked to the transformer secondary coil also changes; hence an EMF is induced in the secondary coil due to Faraday's law of electromagnetic induction.

Actually the transformer is based on two principles:

i> an electric current can produce a magnetic field or electromagnetism;

ii> a changing magnetic field within a coil of wire induces a voltage across the ends of the coil.

Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil.

So far, we understand that transformer works with an Alternating Current or AC voltage.

### What is the Effect of Giving a Constant DC Voltage to a Transformer Input?

Observing the following steps we can see the effects of applying a constant DC voltage input to a transformer:

1. As we know the properties of an inductor v=Ldi/dt, since v is constant here, the i(current) will follow a ramp waveform and will keep on increasing till the core saturates;

2. This means, i will rise to a dangerously high value and then stop changing, if i stop changing then the induced voltage across the primary will be zero(as di/dt=0) thus short-circuiting the DC source;

3. Heavy short circuit current will flow, overheating the coils, resulting in i squared R losses. Temperature rise will exceed safe values and eventually, the apparatus will catch fire;

4. Short circuit currents will result in radial magnetic forces that will rip apart the winding and the wingdings become exposed to the atmosphere. Transformer oil may catch fire under short circuit conditions;

5. So we must never apply a DC voltage to a transformer during operating conditions.

Pulsating DC can be applied to transformers, such as the flux reset occurs in the negative pulse period.

wound up here "Why DC voltage is not Applied in Transformer Input".

And I do have a few questions ffor you if it's allright.

Could it be just me or does it appear like some of the comments come across like left bby
brain dead people? :-P And, if you arre writing at additional sites, I'd lke to
follow anything new you have to post. Would you list of the complete urls of all your

98. Very interesting details you have noted, appreciate iit for posting.
