Właściwości metrologiczne przekładnika Brooksa i Holtza

The paper presents metrological analysis of two-stage Brooks and Holtz transformer which are using in precision measurement circuits. The influence of the main transformer and the auxiliary transformer secondary to the resultant error of two-stage transformer was evaluated. Obtained relations indicates that the dual-stage Brooks and Holtz transformer has a very good metrological properties. Presented analysis was verified by transformer model tests. These considerations and results can be used to design dual-stage transformers.
