单词 phase angle(symbol: ϕ)
释义
phase angle(symbol: ϕ)

Electronics and Electrical Engineering
  • The angle between two vectors that represent two sinusoidally varying quantities of the same frequency (see phase). If the two quantities are nonsinusoidal but have the same fundamental frequency, the phase angle is the angle between the two vectors that represent the fundamental components. Waveforms that have a phase angle of π/2 are said to be in quadrature. If the phase angle is equal to π they are in antiphase.
