An electrical measurement method based on reference energy comprises the following steps; acquiring a first reference signal from a circuit to be measured, wherein the first reference signal is a current signal or a voltage signal; multiplying the first reference signal by a second reference signal to obtain a reference power, wherein the second reference signal is a voltage signal or a current signal; performing time integration on the reference power within a preset time length to obtain reference electric energy; and judging an electrical state according to the reference electric energy. In the present application, electrical detection and fault diagnosis are achieved from the view of electrical energy of each time period, it is particularly analysed with regard to middle and early warning of hidden electrical trouble, so that the electrical detection difficulty is reduced. |
