Abstract: In order to exclude main fault of electrical fast transient/burst(EFT/B) tests, including the meter resetting, drastic measuring accuracy, individual components damaged and so on, based on several prototypes experiment in the meter research and development. Aiming at the disturbed mode and path of the pulse in voltage loop, power loop, current loop, the necessary immunity measure was increased, the key circuit parameters was modified, and software design were improved respectively. The test results show that these measures can inhibit the effect of EFT/B on meter effectively.
Key words: energy meter; electrical fast transient/burst(EFT/B); disturbing
