because it generate heat
A transformer that increases voltage is a step-up transformer.
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
A transformer used to step up or down the value of voltage.
A step-up transformer.
To allow room for oil expansion and contraction. The transformer is completely filled with the oil and when it heats up under load or due to ambient temperatures, the oil has to have a place to go. In the event of colder weather or if the transformer is not under heavy load the oil cools and contracts creating a slight vacuum inside the tank. The conservator acts as a reservoir of oil that can then flow back into the tank so that no air enters it.
Winding copper losses of a transformer can be measured in a short circuit test of a transformer. Impedance voltage is given to the primary and the secondary is often shortcircuited. (some times the reverse is done of this). Full load currents are made to flow in both primary and secondary circuits. This current flow heats up the 2 windings of the transformer. Power consumed at this time gives the transformer copper losses.
The desert heats up faster.
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
A transformer that increases voltage is a step-up transformer.
The sun's energy heats up the Earth's water.
This type of a transformer is known as a step up transformer.
simple step up transformer
A step up transformer is used to step up an AC voltage
A transformer is used to step up or step down a Voltage supply.
A transformer that increases voltage is a step-up transformer.
Transformer is used for stepping up or down the voltage.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
