A System Solution For Terminal DTU/FTU Combined Primary And Secondary Distribution

Application Introduction

Li_Battery_solution_pic_en
In the end of 2016, The State Grid Corporation of China (SGCC) proposed an overall principle: "the automated terminal DTUs/FTUs of the distribution network must take into account the requirements of combining primary and secondary distribution, and must consider replacing traditional electromagnetic transformers with electronic transformers." ADI released a set of chip-scale signal links to satisfy these new applications.

ADI offers:
  • A signal processing solution in compliance with the new requirements of the state grid
  • A design which is high reliability and EMC compliant
  • A design compatible with considerations of the short-term and long-term DTU/FTU variations
