The utility model relates to a multi-station AC voltage testing apparatus which belongs to the electric energy metering technical field. The multi-station AC voltage testing apparatus adopts a movable vehicle body. A high-voltage source, a display detection unit and testing trays are arranged on the movable vehicle body. There are at least two testing trays which are respectively arranged on different support layers of the movable vehicle body. Each testing tray is provided with at least two testing stations. A testing clamp suitable for a product to be tested is arranged on each testing station. The high-voltage source is accessed to the power supply terminal of each testing station in a parallel connection way. The display detection unit comprises display modules corresponding to each testing station. Each display detection module is used for displaying an insulation leakage current property value measured on the corresponding testing station. Multiple electric energy metering products can be simultaneously tested. Each product can be independently displayed and alarm. Problems that a voltage-withstanding tester can only detect one electronic product once and tedious manual wiring is also required are solved.
