Verkköjännitteet

Verkköjännitteet, often translated as mains voltage or line voltage, refer to the electrical potential difference provided by the public power grid. These voltages are standardized to ensure compatibility between electrical appliances and the power distribution system. In most residential and commercial settings, the nominal voltage is typically around 100-130 volts or 200-240 volts, depending on the country or region. This voltage is delivered through a network of power lines, transformers, and substations.

The frequency of the alternating current (AC) associated with these voltages is also standardized, commonly being 50 Hz or 60 Hz. This frequency determines the rate at which the voltage changes direction. Verkköjännitteet are crucial for powering a vast array of devices, from small household appliances to large industrial machinery. Safety regulations and standards are in place to govern the generation, transmission, and use of these voltages to prevent electrical hazards. Variations from the nominal voltage can occur due to factors like load fluctuations and transmission losses, but these are usually kept within acceptable limits.
