The evolution of standard lines of current transformers for high overcurrent capacity

W. K. Dickinson (General Electric Company, West Lynn, Mass.): The subject of high overload-current capacity of current transformers has been one of much interest and has received considerable discussion in recent years — particularly the mechanical overcurrent capacity. In fact, there is still some question regarding the present American Standards Association definition of the term “mechanical overload limit.” It is this angle of Mr. Wentz´s paper that I would like to discuss briefly.
