| Abstract: | This paper fully analyzes all the aspects involved in composite errors of current transformers and illustrates the requirements of composite errors for current transformers in terms of application. Direct measure and indirect measure on composite errors are put forword. The methods are practical and flexible, The paper also presents drawing method of relation curve of accuracy limit factor and secondary burden. Two examples are given on how to draw the curves. |
