What is double voltage double frequency test?
Type your answer here... it is used to find the insulation break down of the conductors from turns to turns and layers to layers.it is aninsulation test for the transformers
What is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
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.
Why desiel is used in transformers?
Transformers use transformer oil as an insulator and to conduct the heat away from the windings. The oil usually flows through a radiator in a closed circuit on high-power transformers.
What is a long in c programming?
It is used with other data types such as long int or long float (=double). The capacity of the data types got increased with long keyword
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.
What types of transformers are used in an x-ray machine?
Auto bots.
Different types of insulation used for transformers?
Most transformers are insulated with polymers or porcelain. Some transformers have an oil based insulation which must be kept dry to remain effective.
What model of phone was in the transformers movie?
To find out the type of phones in the move "Transformers" you would have to watch the movie carefully and identify the types of phones used.
What is the two types of transformer commonly used in industry?
Step-up and Step-down transformers
How do you wire a DPST switch?
A double pole single throw switch. used to switch two lines at the same time.
What is the difference between iron clad double pole switch and double pole single throw switch?
Answer for USA, Canada and countries running a 60 Hz supply service.The difference between a double pole switch and a single pole switch is the use of the switch in the installation or equipment. A double pole switch is used when the voltage from two circuits has to be broken. An example of this is a 240 volt supply. A single pole switch is used where there is only a single supply voltage that has to be broken.

What are the types of transformer?
There are a variety of types of transformers. These include autotransformers, polyphase transformers, leakage transformer, resonant transformers, as well as audio transformers.the decepticons are the bad guys, and the autobots are the good guys. bumblebee and optimis prime are autobots. megatron is a decepticon.
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.
Can a 4 way switch be used in place of a 3 way switch?
No a 3-way is a single pole double throw. A four way switch swaps travelers.
WHAT IS A BREATHER AND WHAT IS IT USED FOR IN TRANSFORMERS?
A breather is used for underwater breathing in the Transformers Franchise. Most transformers have this feature, however, there are some who don't, like Pptimus Orime, Negatrom and more.
