Abstract: The interference mechanism of electrical fast transient/burst(EFT/B) was analyzed.Taking an electric meter with load as research object,sensitive frequency rang of the electric meter with load under conditions of interference was obtained through experimental research of influence of electrical fast transient/burst on input of power supply in different voltage levels,different polarities and different interference frequencies.Finally notices of experimental operation were summarized.The conclusions have a certain reference value to design of electric meter and its anti-interference measures.
