Beschreibung
Zusammenfassung:	The invention provides a synchronous phasor measurement method, device and system, and the method comprises the steps: obtaining a parameter set of a cable, the parameter set comprises a first current value of a first end of the cable and a second current value of a second end of the cable, and if a difference value between the first current value and the second current value is greater than or equal to a first preset current threshold value, determining that the cable is in a synchronous phasor measurement state; and if yes, determining that the aging degree of the insulating layer of the cable is the first aging degree, and displaying the aging degree. The aging degree of the insulating layer of the cable is determined by acquiring the first current value of the first end of the cable and the second current value of the second end of the cable, and then the aging degree is displayed, so that an operator can conveniently determine the specific aging degree of the insulating layer of the cable. In addition, t
