Developed electronic current transformer related standards

Production and living the high demand for power on the power system safe, reliable and economic operation put forward higher requirements, the traditional current  mcb circuit breaker  power system can not meet the development needs of current measurement for power  electric transformer  new technologies and new method has become imperative. To this end, the International Electrotechnical Commission (IEC) has developed an electronic current transformer related standards, current  air circuit breaker  for the new development has laid a good foundation. Active optical current transformer is electronic current transformer is an important direction of development, at home and abroad has been a lot of research work carried out and made ​​practical many valuable experience.
