Leiterspannung

Leiterspannung, also known as line voltage, refers to the electrical potential difference between two points in an electrical power system, typically measured in volts (V). It is the voltage that is transmitted over long distances from power plants to substations and then to consumers. In alternating current (AC) systems, the line voltage is the root mean square (RMS) value of the voltage waveform.

The term "Leiterspannung" is commonly used in European countries, particularly in German-speaking regions. It is distinct

In three-phase AC systems, the line voltage is the voltage between any two of the three phases.

Leiterspannung is a critical parameter in the design and operation of electrical power systems. It influences
