Perusjännite

Perusjännite is a Finnish term that translates to "basic voltage" or "nominal voltage." It refers to the standard voltage level that is typically supplied to a consumer or used in a particular electrical system. This voltage is the intended operating voltage for most electrical devices and appliances designed for that region. For example, in Finland, the nominal mains voltage for households is 230 volts AC. This perusjännite is crucial for ensuring that electrical equipment functions correctly and safely. Deviations from the perusjännite can occur due to various factors, such as voltage drops in transmission lines or fluctuations in the power grid. However, electrical devices are designed to tolerate a certain range of voltage variation around the perusjännite. Understanding the perusjännite is important for selecting appropriate electrical equipment and for troubleshooting electrical issues. It is a fundamental concept in electrical engineering and everyday electrical use.
