The invention provides a wireless communication measuring system for current of a build-in arrester, which is used for measuring the current or the voltage flowing through arrester cores. The system mainly consists of multiple measuring transducers, a relay transducer, a central controller and an upper PC (Personal Computer). The system is characterized in that the measuring transducers which are respectively placed inside multiple arrester cores are in series connection with resistor discs inside the arrester, and the measuring transducers send the measured result on the current flowing through the cores inside the arrester to the relay transducer through a wireless transmission module for signal conditioning. The measuring transducers provided by the invention are built inside the arrester cores, measured parameters are all information related to the interior of the arrester, and the interference of outside information is avoided.
