Abstract: In recent years, electrical equipment burnout caused by voltage failures occur frequently in the power distribution system of gas stations. From the perspective of causes of voltage faults, it can be divided into unqualified power grid voltage quality on the power supply side, zero shift of transformer caused by unbalanced three-phase load on the user side, and voltage mutation caused by loose contacts on the user side. Aiming at these voltage failure causes, the solutions and corresponding measures are put forward.
