sähkövaihetta
Sähkövaihetta refers to the concept of electrical phase in alternating current (AC) systems. In an AC circuit, the voltage and current oscillate sinusoidally over time. This oscillation can be represented as a wave. Electrical phase describes the position of this wave at any given moment in time relative to a reference point, often the zero crossing of the wave.
In a single-phase system, there is typically one voltage waveform. However, in polyphase systems, such as two-phase
The phase of an electrical signal is crucial for the efficient operation of AC machinery and power
