Eenfase

Eenfase, also known as single-phase, refers to an electrical power distribution system that uses a single alternating current (AC) voltage waveform. This system is commonly used for residential, commercial, and small industrial applications where power requirements are relatively low.

In a single-phase system, the voltage alternates between positive and negative values in a sinusoidal pattern, typically at a frequency of 50 or 60 hertz (Hz). The key characteristic of a single-phase system is that it delivers power through two conductors: a live (hot) wire and a neutral wire. Some systems may also include an earth (ground) wire for safety.

Single-phase power is widely used in household applications, such as lighting, appliances, and small motors. It is also commonly found in office buildings, shops, and other small-scale facilities. However, it is generally unsuitable for large motors, industrial machinery, or high-power applications due to its limited starting torque and lower efficiency compared to three-phase systems.

The voltage levels in single-phase systems can vary depending on the region and application. Common residential voltages include 120 volts (V) in North America and 230 V in many parts of Europe and Asia. In some cases, a single-phase system may use a higher voltage, such as 240 V or 400 V, for specific industrial or commercial uses.

One advantage of single-phase systems is their simplicity and lower cost of installation compared to three-phase systems. They require fewer conductors and simpler wiring configurations, making them easier to maintain. However, they are less efficient for certain types of loads, particularly those requiring high starting currents or continuous power delivery.

In summary, eenfase systems are a fundamental part of electrical infrastructure, providing reliable and efficient power for a wide range of applications where high-power demands are not required.
