A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
They consist of primary and secondary coils wound around a core made of ferromagnetic material.
Step-up transformers increase voltage for long-distance power transmission, while step-down transformers decrease voltage...

Transformer losses refer to the energy losses that occur during the operation of a transformer.
Transformer losses include copper losses and iron losses.
Copper losses occur due to the resistance of the transformer windings.
Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.
Copper losses can be minimized by using larger conductor sizes and reducing the resistance of ...
Efficiency of transformer is the ratio of output power to input power.
Efficiency is affected by factors such as core losses, winding resistance, and load impedance.
Efficiency can be improved by using high-quality materials, proper design, and regular maintenance.
Efficiency is expressed as a percentage and can range from 50% to 99% depending on the transformer type and application.
Non-sparking equipment and lights are used in hazardous environments to prevent explosions.
Non-sparking tools are made of materials that do not create sparks when struck or rubbed against each other.
Non-sparking lights use LED technology and are enclosed in a housing that prevents sparks from escaping.
These techniques are commonly used in industries such as oil and gas, chemical, and mining.
Examples of non-sparking too...
