jednofazowych

Jednofazowych refers to single-phase electrical systems. In an alternating current (AC) power system, a single-phase supply is typically delivered through two wires: one active or live wire and one neutral wire. The voltage in the active wire oscillates between positive and negative values relative to the neutral wire. This type of system is common for residential and small commercial applications where the power demand is relatively low.

The characteristic of a single-phase system is that the power delivered fluctuates sinusoidally over time, reaching zero twice in each cycle. While this fluctuation is generally not noticeable in most household appliances, it can be a consideration for larger motors or equipment requiring a more constant power supply. Single-phase power is generated by a single alternating voltage waveform.

Compared to three-phase systems, single-phase power is simpler to generate and distribute. It requires less complex wiring and equipment, making it more cost-effective for low-power applications. However, for high-power industrial machinery, three-phase power is preferred due to its continuous and more consistent power delivery, which is more efficient for running large motors and heavy loads. The term "jednofazowych" is a Polish adjective meaning "single-phase."
