| Abstract: | For overcoming the limitation of analog devices such as temperature drift and time drift and etc, a ADE7759 chip which can be used as a digital integrator in electrical current transformer is adopted. And the usage of ADE7759 is introduced in brief. It is proved by the accuracy experiments that the ECT can meet at 0.2 class in IEC 60044-8. |
