The invention relates to a method of wirelessly transmitting reference phasor in analog or phasor measurement. The method is characterized by comprsing the following steps: voltage reference phasor is acquired, the acquired voltage reference phasor is wirelessly transmitted in a wireless transmission mode, the above voltage reference phasor is received by adopting a wireless receiving mode in a measurement place, and the received voltage reference phasor is used to complele the phasor measurement work at the measurement place. The invneiton provides an analog phasor measurement method based on the wireless reference phasor transmission mode, a phasor measurement experiment can be carried out on a secondary current circuit in need of phasor measurement at any place, the problem that current phasor measurement can not be carried out when no reference voltage phasor place (such as an outdoor current transformer terminal box, a 2/3 connection mode bus protection screen and the like) exists can be solved, and the problem that a conventional phase meter, a volt ampere characteristic tester and other measurement mode depend on measurement place reference phasor can be solved.
