The type of VCB coil is generally a copper coil.
VCB coils are typically made of copper due to its high conductivity and durability
Copper coils are preferred for VCBs as they provide efficient current flow and are resistant to heat
Some VCB coils may also be made of aluminum, but copper is more common
Transformer losses include copper losses and iron losses.
Copper losses are caused by the resistance of the copper windings and increase with the square of the current flowing through the transformer.
Iron losses, also known as core losses, are caused by hysteresis and eddy currents in the transformer core material.
Other losses may include stray losses, dielectric losses, and mechanical losses.

Power distribution is the process of delivering electricity from power plants to consumers through a network of transmission and distribution lines.
Electricity is generated at power plants using various sources such as coal, natural gas, nuclear, or renewable energy.
The electricity is then transmitted at high voltages over long distances through transmission lines to substations.
At substations, the voltage is reduced a...
