Question
Mention various energy losses in transformer device
Advertisements
Solution
Energy losses in the transformer:
Flux leakage, due to poor design of the core and air gaps in the core
Resistance of the windings, which leads to loss of energy due to heat produced
Eddy currents, due to alternating magnetic flux in the iron core, which leads to loss due to heating
Hysterisis, frequent and periodic magnetization and demagnetization of the core, leading to loss of energy due to heat

Long distance power transmissions
The large-scale transmission and distribution of electrical energy over long distances is done with the use of transformers. The voltage output of the generator is stepped up. It is then transmitted over long distances to an area sub-station near the consumers. There the voltage is stepped down. It is further stepped down at distributing sub-stations and utility poles before a power supply of 240 V reaches our homes.
If the secondary coil has a greater number of turns than the primary, ______.
