The invention relates to an electric three-core cable phase current wireless monitoring system, and belongs to the technical field of current measuring equipment. According to the technical scheme, acurrent acquisition device (1) is connected with a monitoring center (3) through a wireless communication module (2); the current acquisition device (1) comprises three magnetic sensors (11); the three magnetic sensors (11) and cable three-phase core wires are collimated and mutually deviated by 120 degrees; the wireless communication module (2) comprises a data acquisition node (21) and a ZigBeecoordinator (22); and the monitoring center (3) comprises an ARM processor (31), a display module (32), a storage module (33) and an alarm module (34). The system has the beneficial effects that stateinformation of each phase current in a three-core cable can be displayed in real time; all-weather online monitoring of three-core cable current operation conditions is achieved; current informationis transmitted to the monito
