【Abstract】 In the measure of power system and its protection,current transformer and measure appliance cooperation can measure system’s current and electricity. Cooperating with relay,it can protect system and equipment from excess current,overload,and earthing etc. In the light of the high accuracy and little transformation ratio current transformer’s special instructions,the article expounds the function demanded,points out the special process method of high accuracy and little transformation ratio current transformer on its construction design,and gives an example. By operation and application to actual project,the result shows that this kind of design method is good,accords with national standard,satisfies requirement of project.更多还原
