Abstract :
The causes of error with increasing frequency in current transformers of existing design are examined. A new approach in design is suggested and equations are developed from which the performance can be calculated for a variety of operating conditions over a wide band of audio frequencies. Practical details are given of a group of multiratio transformers rated from 5/5 to 400/5 designed for the range 400 cps to 20 kc.
