摘　　要：介绍空载电流互感器。它是继零磁通电流互感器、双级电流互感器和电流比较仪之后的又一种新型的电流比例标准。在相应的互感器校验仪上作为标准,其准确度可比普通互感器高2～3级,接近于双级电流互感器。但它没有补偿绕组,用于制作0.01级以下电流互感器,安匝数低,使用更方便。No burden current transformer is introduced in this paper. It is a new current ratio standard after the zero flux current transformer, two stage current transformer and current comparator. Just like a two stage current transformer, the accuracy class could be improved two or three grades than that of a common current transformer. When used to made a current transformer with accuracy class lower than 0.01, there are no compensation windings in it and the ampere-turns is much smaller, so it is more convenient to use.
