egyfázisúak

Egyfázisúak refers to single-phase electrical systems. These are the most common type of electrical power distribution used in residential and small commercial buildings. A single-phase system uses two wires: one for the live or hot wire and one for the neutral wire. The voltage in the live wire alternates in a sinusoidal pattern, creating a single alternating current (AC) waveform. This waveform is what powers most household appliances, lighting, and electronic devices.

The generation of single-phase power typically involves a single coil within a generator rotating within a magnetic field. This process induces a single alternating voltage. The distribution of single-phase power is simpler and less expensive than three-phase systems, which is why it is prevalent for lower power requirements. The voltage in a standard single-phase system can vary by region, but common voltages include 120 volts in North America and 230 volts in Europe and many other parts of the world. While sufficient for most domestic needs, single-phase power is less efficient for larger, industrial machinery that requires higher starting torque and more consistent power delivery, where three-phase systems are preferred.
