pääsyöttöjännite

Pääsyöttöjännite, often translated as main supply voltage or primary voltage, refers to the voltage supplied to a device or system from the primary power source. This is the initial voltage that enters the electrical circuit, before any transformations or modifications occur. For example, in a household electrical system, the pääsyöttöjännite is the voltage provided by the utility company to your home, typically around 230 volts in many European countries.

In the context of transformers, the term pääsyöttöjännite specifically denotes the voltage applied to the primary winding. The transformer then steps this voltage up or down depending on the number of turns in its secondary winding. Understanding the pääsyöttöjännite is crucial for ensuring compatibility between power sources and electrical equipment, preventing damage and ensuring safe and efficient operation. It's the starting point from which all subsequent voltage levels within a system are derived.
