A 3-phase waveform consists of three sinusoidal waveforms that are 120 degrees out of phase with each other.

• A 3-phase waveform is used in electrical power systems.

• Each phase of the waveform has a peak, trough, and zero-crossing points.

• The three phases are typically labeled as A, B, and C.

• The waveforms are evenly spaced and have a frequency of 50 or 60 Hz.

• The waveforms can be represented graphically as three sine waves.
