The invention relates to a device and method for rapidly seeking a fault
electric energy meter, and belongs to the technical field of power supply maintenance. According to the technical scheme, callipers of a clip-on
ammeter clamp a line loading the live wire outlet end (2); an
electric energy meter is adjusted to be in a current reading state, the same time is set through a
timer, and then an observation current value of the clip-on
ammeter and a current reading value of the
electric energy meter are observed separately; if the error of the current values of the clip-on
ammeter and the electric energy meter within the same time is 0.5 A or above, it is determined that the electric energy meter is out of order. According to the device and method for rapidly seeking the fault electric energy meter, the fault electric energy meter can be sought visually and rapidly, and the work efficiency is improved; the method is easy to operate, the accuracy can be guaranteed, and a wiring error caused by
assembly and disassembly of the electric energy meter is greatly avoided; the power
off time is shortened, misunderstanding of users is reduced, and the
workload of workers is relieved; in the background art, one hour is needed to disassemble and assemble an electric energy meter for detection, whether the electric energy meter is out of order or not can be judged within one minute at present, and the work efficiency is greatly improved.
