Single-phase electronic power saving device

The utility model, which belongs to the electronic power saving field, relates to a single-phase electronic power saving device, comprising a capacitor C, an inductor L, a discharging resistor R2, a resistor R1 on an indicating lamp circuit, an indicating lamp D and a protective tube F. Specifically, the protective tube F and the inductor L are connected in series with the capacitor C; and the resistor R1 on an indicating lamp circuit, the indicating lamp D and the discharging resistor R2 are connected in parallel with the capacitor C. According to the utility model, the circuit has a display capacitive effect for a power grid and is accessed to a power grid having an inductive load, thereby substantially reducing a virtual work currents; the inductor L is introduced to inhibit ultra-harmonics in the power grid, thereby reducing losses of an electrical system and thus achieving an objective of cutting down electricity costs of users. Therefore, when the single-phase electronic power saving device that is desi
