— the ability to measure the phase shift of two parameters that change according to the law of a sinusoid. These can be two electrical signals (for example, phases in a three-phase network), or characteristics of one signal (for example, delay / advance of the current relative to the voltage). The methods of applying such measurements can be different: for example, the first of the described options is used to determine the quality of a three-phase power supply, the second is used to assess the power factor (“cosine phi”) when working with a reactive load.
