The invention relates to an electric network grounding compensation device based on an arc suppression transformer. The electric network grounding compensation device comprises the arc suppression transformer connected with an electric network bus, wherein the arc suppression transformer is a three-phase five-pole type arc suppression transformer of which the primary side winding is in star-shaped connection with a neutral point directly grounded, and the secondary side winding is of an opening delta connection type, a secondary side opening end of the three-phase five-pole type arc suppression transformer is connected with an active inverter regulating device used for outputting compensating voltage to the arc suppression transformer, and the controlled end of the active inverter regulating device is connected with a controller used for controlling the active inverter regulating device to output compensating voltage. According to the electric network grounding compensation device, the number of equipment mou
