Abstract:
For the electrical fast transient(EFT)noise immunity problems of the Multifunctional Meter,the mechanism of production and harassment of EFT are analyzed,the treatment method of EFT is studied,and a solution to EFT problem of power input port of meter is put forward.The experimental results show that the EFT noise immunity level of multifunctional meter is efficiently improved,and the demands of GB/T 17626.4-2006 are reached.
