摘要：

Electronic current transformer (ECT) is a novel Current measurement instrument. The active ECT is based on Rogowski coil and has more excellent performances than traditional current transformer (CT), such as high accuracy, long-term stability, great flexibility and etc. In order to recovery the primary current, the ECT has to include ail integrator. The all-digital active ECT presented here uses a digital integrator instead of an analog one, and it transmits data, processes data and output digitally. That means all parts of the ECT except the sensing coil are digital. The all-digital design improves the temperature stability and electro magnetic interference (EMI) immunity of the ECT greatly.
