The invention relates to a mobile assessment and measurement method and device capable of being operated in an electrified manner. The device comprises an intelligent remote fee control meter, currenttransformers capable of being opened and closed and a plurality of connecting wires, wherein the connecting wires include two transformer connecting wires and two power connecting wires, one end of each transformer connecting wire is provided with a transformer plugging terminal, and the other end is connected with the current transformer; and one end of each power connecting wire is provided with a power plugging terminal, and the other end is connected with a wire clamp. Preferably, the intelligent remote fee control meter is a three-phase four-wire intelligent remote fee control meter, andthree current transformers capable of being opened and closed are arranged. In the specific implementation, the fee control meter is installed in a low-voltage power meter box, and the low-voltage power meter box is fixed on a pole through a support frame. The mobile assessment and measurement device is short in equipment installation time and small in workload, the equipment can be used in different transformer areas in turn, the equipment are transferred to another transformer area for use after completing electricity measurement in one area, and the quantity of required equipment is reduced.
