Explain transformer? What is on transformer nameplate? Where is star connection used? Where is delta connection used?

Question

Accepted Answer

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformer nameplate includes information such as rated power, voltage, current, frequency, and efficiency.
Star connection is used in power distribution systems to connect three-phase loads.
Delta connection is used in industrial applications where high current loads are present.
Transformers are essential in stepping up or stepping down voltage levels for transmission and distribution of electricity.
Transformer efficiency is crucial for minimizing energy losses during power transfer.
