Study on High-accuracy Current Transformer with Micro Flux
Huang Ye-an · Electrical Measurement & Instrumentation · 2010
Developing a high-accuracy and low current transformer(CT) is the common concern of electric instruments industry at the moment.In this project,a high-accuracy and low current transformer with double-core and double winding structure is desigened based on the principle of micro flux and the method of passive compensation errors.It is advantageous to simplify the structure by using the principle of micro flux in the range of allowable errors.The CT series micro current transformer which is designed in this project have passed the test,and the precision is up to 0.02%.
