Specifically, a voltage signal of a circuit to be detected is obtained through the voltage sensor 101, and then a first voltage value u=ucos (ωt) is obtained through the voltage tracker 102, wherein U is a preset voltage; ω is the angular frequency (ω=2pi f), and t is the period of the voltage signal.

The current sensor 201 acquires a current signal of a circuit to be detected, the current signal is transmitted to the current tracker 202, and the current tracker 202 converts the current signal to obtain a first current value. Specifically, a current signal is obtained through the current sensor 201, and the current signal is output, and after the current tracker 202 obtains the current signal, the current signal is converted into a first current value i=icos (ωt+θ), where I is a preset current of the circuit to be detected; omega is the angular frequency; θ is the phase difference between the voltage and the current. After obtaining the first current value, the second divider 302 obtains the first current value, and divides the first current value by the current amplitude corresponding to the circuit to be detected, to obtain the second current value as cos (ωt+θ).
