Voltage and Frequency of 3 Phases Electricity of the World

Although single-phase power is more common today, three-phase power is still chosen as the power source of choice for many different types of applications. The generator of the power station provides three-phase electricity. This is a way to provide three times the power along three wires, and power can be supplied through two wires without having to increase the thickness of the wires. It is commonly used in industry to drive motors and other equipment.

In its essence, three-phase electricity is smoother than single-phase or two-phase electricity. It is this more consistent power that allows machines to operate more efficiently and have a longer life than related machines operating in other stages. Some applications can work with three-phase power, but these methods are not suitable for single-phase power at all.

Please note that since three-phase electricity is rarely used for household purposes, the following table is only relevant for electricians, electrical engineers and other technicians.
