First of all, the current transformer is an instrument and equipment that converts a large current into a small current on the secondary side according to the principle of electromagnetic induction. The current transformer is composed of a closed iron core and windings. Its primary winding has very few turns and is stringed in the…
The current transformer is an instrument that accurately converts a large amount of current on the primary side into a small amount of current on the secondary side according to the magnetic effect of the current. The current transformer is composed of a closed iron core and windings. The number of primary winding turns is…
Understanding the Differences Between Current Transformers and Zero Sequence Current Transformers Current transformers (CTs) and zero sequence current transformers (ZSCTs) are essential components in electrical systems, playing critical roles in protection and measurement. Understanding the differences between these two types of transformers is crucial for engineers and technicians working in electrical safety and system design.…

Current-type signals, the external characteristics of the ideal situation, is equivalent to a very large voltage source in series with a very large internal resistance. In this way, when the load impedance is much smaller than its internal resistance, the current is always equal to its “short circuit current”. Its main advantages are: as long…
In order to obtain the best suppression effect on common mode interference, the common mode inductor core must have high magnetic permeability and excellent frequency characteristics. In the past, most of the ferrite core materials used for common mode inductors have excellent frequency characteristics and low cost advantages. However, ferrite also has some insurmountable weaknesses,…
