Description
technical field [0001] The embodiment of the present application relates to the field of electrical measurement technology, in particular to a device and method for real-time and accurate online monitoring of resistive current by a Zigbee-based zinc oxide arrester. Background technique [0002] The zinc oxide arrester has good nonlinear volt-ampere characteristics, so that the current flowing through the arrester at normal operating voltage is extremely small (microampere or milliampere level); when the overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is released , to achieve the effect of protection. In addition, the zinc oxide arrester does not need to be connected in series with the spark gap, and has a simple structure, reduced volume, and good anti-fouling performance, which can avoid the unstable discharge voltage of the series spark gap due to the pollution outside the porcelain sleeve; the zinc oxide valve plate has a large flow capac...
