Fasespanningen

Fasespanningen, often translated as phase voltages, refer to the voltage differences between the individual phases and a neutral point in a three-phase electrical system. In a balanced three-phase system, three alternating voltages are generated, each with the same frequency and amplitude but offset in phase by 120 degrees. The phasespanning is the voltage measured from one of these phases to the neutral conductor, which is typically grounded.

These voltages are crucial for the operation of many electrical devices and systems, particularly in industrial and commercial settings. The magnitude of the fasespanning depends on the specific design of the electrical distribution system. Common values for fasespanning in low-voltage systems include 120 volts (in North America) or 230 volts (in Europe and many other regions).

Understanding fasespanning is essential for electrical engineers and technicians when designing, installing, and maintaining electrical equipment. It directly impacts the voltage experienced by single-phase loads connected between a phase and the neutral. In contrast to fasespanning, phase-to-phase voltage (or line voltage) is the voltage measured between any two of the three phases. The line voltage is typically the square root of three times the fasespanning in a balanced system. Incorrectly connecting loads or failing to account for the correct fasespanning can lead to equipment damage or malfunction.
