The article proposes a principle for constructing contactless primary zenith angle converters based on sine-cosine rotating transformers. This principle involves isolating signals caused by changes in the mutual induction coefficient between the primary and secondary windings and suggests using a reference signal to establish the required functional relationship. The study revealed that errors in displaying the sine and cosine functions stem from the identical maximum inductive resistances of mutual induction, active and inductive components of the secondary load circuits, and the asymmetry of the zero points, characterized by a nonperpendicular electrical angle. It has been determined that to enhance measurement accuracy, it is essential to eliminate the reciprocity of signal phases from the parameters of signal circuits.
