kolmivaihejärjestelmis
Kolmivaihejärjestelmä, often translated as three-phase system, refers to an alternating current (AC) electrical power system that uses three conductors, each carrying a sinusoidal current. These currents are identical in frequency and amplitude but are out of phase with each other by 120 degrees. This phase difference is crucial for the efficient generation, transmission, and utilization of electrical power.
The primary advantage of a three-phase system is its ability to deliver a constant amount of power,
In power generation, three-phase alternators are used. The rotating magnetic field within the alternator induces voltages
At the distribution level, three-phase power is commonly used for industrial facilities and larger commercial buildings.
