What is the weight of 462 kg of transformer oil?
The oil should be greater than 100M Ohms resistance. If a flash over occurs within the transformer the oil has to be replaced
How much does transformer oil weigh?
7.6 pounds/gallon
What is the difference between a step-up transformer and a step-down transformer in terms of their voltage conversion capabilities?
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
What happens when frequency is increased of transformer?
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.
What is the difference between a step-up and step-down transformer?
A step-up transformer increases voltage, while a step-down transformer decreases voltage.

What is the density of transformer oil?
Density of Transformer Oil at 29.5oC is 0.89g/cm3.The exact density of transformer oil depends upon the manufacturer but, expressed in SI units, is typically a little less than 900 kg/m3 at 20oC. The J&P Transformer Book states that 'a limit of 895 kg/m3 at 20oC ensures that the temperature (of the oil) must fall to -20oC before the density of the oil would exceed that of ice' -thus ensuring that if ice forms, then it would remain at the bottom of the tank.
Where does hysteresis in a transformer depend on?
The power lost by hysteresis depends on the peak flux density in the core. If the transformer is getting hot even when on no load, it should be run at a lower voltage.
Why is the purpose of using core in transformer?
To maximise the magnetic linkage and flux density between the primary and secondary windings.

How do you find the turns ratio of the transformer if the magnetic flux density is known?
you'll need more information, like the voltage drop (step-down transformer) or the voltage increase (step-up transformer). some transformers are also used to electrically isolate a circuit (1:1 ratio) e.g. a stereo amplifier
How the losses will reduce if you keep the flux density in high level in power transformer?
The flux density is set at the most the core material can stand, which for standard laminated transformer iron is around 1 Weber per square metre. Based on that and the cross-section area of the core, the volts per turn figure is calculated for both the primary and the secondary winding. If the operating voltage stays constant, so will the flux density and the iron losses.
What will happen to output of a transformer rated at 50 volts 60 hz when its powered by 115 volts 120 hertz versus 115v 60h?
A 50 volt 60 Hz transformer would work well at 100 volts 120 Hz, because the peak flux density in the core would be unchanged. Provided the insulation remained OK the VA rating of the transformer would be doubled. Running it at 115 v 60 Hz would probably damage the transformer even on no-load because the core losses would be increased a lot with the flux density running at double the designed amount.
What is a half transformer and a half transformer?
a hole transformer
Why induction transformer called rotating transformer?
Transformer has windings
