Demagnetization

If the current transformer is cut off at a large current, or the secondary winding is accidentally opened during operation, and after a test with a DC current, residual magnetism may occur in the core of the transformer, which will reduce the magnetic permeability of the core. Affects the performance of the transformer; therefore, before…

The Primary Winding Structure of The Current Transformer

The primary winding structure of the current transformer has two forms of single-turn type and multi-turn type. Single-turn type: The winding is only one turn at a time, and the structure is relatively simple. The primary current is more than 300 to 600A. It is divided into two types: bar type and bus bar type.…

Basic Structure of Current Transformer

Current transformer is mainly composed of a primary winding,a secondary winding and an iron core, and there is insulation among the primary, secondary and iron cores. In order to improve the accuracy of the current transformer, the error of the current transformer is generally compensated.In addition to the above-mentioned primary and secondary windings and cores,…
