What are the functions of current transformers and the difference between current transformers and voltage transformers?
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
Why peak voltage of the load is smaller than the voltage from the transformer output?
The voltage appearing across a load is always smaller than the no-load voltage of any voltage source -e.g. batteries, generators, or transformers. In simple terms this is because all these voltage sources have internal resistance or impedance which results in an internal voltage drop when the source delivers a load current. The resulting voltage, therefore, is always the difference between the no-load voltage and the internal voltage drop. A measure of the difference between a source's no-load and full-load voltage is termed its 'voltage regulation'.
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
What happens when unequal voltage ratios of transformers used in parallel operation of transformers?
You cannot connect transformers of different voltage in parallel. This is because circulating currents will be set up between the two transformers that may exceed their rated currents.

To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
How can transformer oil be used in transformers with voltage rating above its breakdown voltage?
In this circumstance, the clearance between components at different potential must be increased.

Why should someone generate power at 220 V?
Only small personal generators generate a voltage of 220 volts. This level of voltage is used usually during power outages. For voltages that power the electrical grid, the voltage is generated at a much higher voltage and then transformed by the use of transformers, into the voltage that is required by different distribution services.
What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
Electrical Properties of Transformers why you use it?
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
What is The voltage that is provided by the transformers?
The secondary voltage.
How does AVR on generator work?
The function of AVR is to automatically regulate the voltage of Generators. As the terminal voltage of a generators drops the AVR boosts the voltage.
What is zero voltage regulation in transformers and what it means?
'Zero voltage regulation' indicates that there is no difference between its 'no-load voltage' and its 'full-load voltage' -this is only the case for an 'ideal' transformer.
Frequency voltage and amperage must be equal when ac generators are operated in parallel?
Frequency and voltage, yes. Amperage - desirable but not mandatory. Paralleled generators that are equally sized generally have a load balancing control that accomplishes this function. Generators that are of different ratings may be loaded to different current levels because of their capacity limitations.
