What is the meaning of dislocation in electricity?

Dislocation in electricity refers to the phase difference between the waveforms of two sine waves in the same period. According to the relevant public information, the phase describes the time difference between the starting point of the waveform and a specific moment, expressed in terms of angle or time. In electricity, dislocation usually refers to the phase difference between two sine wave voltages or currents in an AC circuit. When the phase difference of two sine waves is 0 degrees, they are completely in phase, and when 180 degrees, they are completely out of phase, and the phase difference is between 0 degrees and 180 degrees.
