Oh, dude, a low impedance transformer on regulation? It's like having a really chill friend who always has your back. Basically, a low impedance transformer helps maintain a stable output voltage even when there are fluctuations in the input voltage. So, it's like the transformer saying, "I got you, bro," and keeping things running smoothly.
What else can I help you with?
What effect does low impedance have on voltage regulation?
raised voltage output
What effect does transformer has a very low impedance on short circuit current?
Oh, dude, when a transformer has super low impedance, it's like opening up the floodgates for short circuit current to flow through, man. It's basically like giving a green light to a bunch of rowdy electrons to party hard and cause a massive current spike. So yeah, having a transformer with very low impedance amps up the short circuit current big time.
How do you convert percent impedance of transformer to impedance value?
The apparent impedance looking into a transformer from one side will not be the same as looking in it from the other, which is why percent impedance is used. If you are looking from the high voltage winding (I'm labeling #1) to the low voltage winding (#2), you must scale the percent impedance as follows: (% impedance) x (Winding #1 nominal voltage)^2 / (transformer base VA)
Why low power factor wattmeter is used for open circuit test of transformer?
For open circuit test of transformer, the secondary is open circuit and the circuit impedance is largely inductive due to the core impedance having high L as compared to R. hence the power factor is reduced, thus , we use low power factor wattmeters.
More the transformer impedance less the fault current... so is a high value of transformer impedance good for it?
It depends a lot on the application, i would go with low impedance transformers if am using the transformers for distribution as it will really increase the the maximum fault current. If am using the transformers as step up specially for generators or to charge capacitors, using a high impedance transformer is a good idea as it will decrease the inrush current of the system. you have to see your application and decide what fit that best.

What will happen on the regulation if a transformer has a very low impedance?
If a transformer has very low impedance, it may lead to higher inrush currents during startup, potentially causing damage to the transformer and connected equipment. Additionally, low impedance can result in reduced voltage regulation, making it difficult to maintain stable output voltage under varying load conditions. This can also lead to increased losses and overheating, ultimately impacting the transformer's efficiency and lifespan. Proper design and protection mechanisms are essential to mitigate these issues.
What type of transformer configuration will you select to design a high input impedance and low output impedance amplifier?
main volage

What happens if dc supply is connected to incomer of transformer?
If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.
What is the difference between Ohm and Ohm CT in impedance of an audio transformer?
The side of the transformer that has the ohm CT which translates into a winding on the transformer that has a center tap . This side of the transformer was likely attached directly to the audio output transistors set up in push pull configuration. This is what the center tap is for. This side of the transformer would have a higher impedance and is directly driven by the power supply to provide amplification The transformer also isolates the amplifier voltage from the other side which is of low impedance. This may be in the range of 8 to to 16 ohms which would be directly tied to a speaker.

What is percentage impedance?
In electrical engineering, the percentage impedance of a transformer is the voltage drop on a full load, which is expressed as a percentage of the specified rated voltage. It's measured by conducting a short circuit test.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
Can impedence inversion be obtained by a short circuit stub?
No, impedance inversion cannot be achieved with a short circuit stub. A short circuit stub will have a low impedance at the point where it is connected, which will not invert the impedance at that point. Impedance inversion can be achieved using techniques such as a quarter-wave transformer or a transmission line with specific impedance characteristics.
