Abstract
The causes of error in inductive voltage dividers are examined in detail, and equations are developed from which the voltage ratios may be predicted with an uncertainty not exceeding 1 part in 108. Experimental methods for measurement of the voltage ratios to an accuracy of within 2 parts in 109 of the input-voltage vector are fully described, together with techniques by which the constituent parts of the overall error may be isolated. The paper also describes an improved method of winding decade inductive dividers and gives specifications for multidecade devices in which the errors predictably will not exceed 1 part in 108 at 400Hz or 5 parts in 108 over the whole frequency range 40-1592 Hz.Keywords
