The realization of the interface between electronic transducer and measurement or protection device is of great significance.The function of merging unit which is the key element of the interface is simply introduced in this paper.Considering the characteristics of the interface
a new realization method of the interface to electronic instrument transformer based on FPGA & DSP is proposed.By using FPGA and DSP together
the merging unit synchronism
the receiving and treatment of multi-channel data
and the function of communicating in Ethernet are finished.The method has met the needs(high speed and reliability) of the electronic transformer and has practical value for application.
