An electrical transformer or electrical choke and a method for operating the electric transformer or the electric induction coil

摘要

It is an electrical transformer or an electrical inductor as well as the proposed a method. The device comprises windings (4), which by means of a tensioned clamping element (10) are loaded with pressure. An extension of the clamping element (10) substantially in the pulling direction (z), by means of an optical sensor (12) can be detected.
