Abstract :
Electronic Current Transformer (ECT) is an important equipment when constructing a major digital substation. The power supply of the ECT is intended solely for providing the DC power supply that could ensure the data collecting system´s normal working. And which is the key way to ensure the reliability and accuracy of ECT. A new model of the power supply based on the characteristics of ECT is proposed: the UPS system, which utilizes a special current transformer and optical power supply as an overall. In order to fit for the urgent requirement of the digital substation, a hardware circuits is designed to realize the proposal. the research of electronic current transformer ECT attracts more and more attention.
