Claim 14:
15. The non-transitory computer-readable storage medium of claim 14, wherein the determining the current voltage of the voltage dividing capacitor in the voltage measuring device comprises:
acquiring a detected voltage of the voltage dividing capacitor in the voltage measuring device; the detected voltage being a voltage collected under a combined effect of the reference AC power supply and the voltages of the three phase conductors; and
decomposing the detected voltage to obtain a first decomposition voltage of the voltage dividing capacitor under separate effect of the voltages of the three phase conductors at the frequency of the AC power supply, and a second decomposition voltage of the voltage dividing capacitor under separate effect of the reference AC power supply at the frequency of the reference AC power supply.
