5.The error is inversely proportional to the magnetic permeability of the core.
Therefore to improve the magnetic properties of the core material is the main way to reduce the size of the current transformer for measurement, especially for the current transformer with higher accuracy.
6.The error of the transformer is proportional to the magnitude of the secondary load.
In fact, when the secondary load increases, the magnetic density of the core increases, and the magnetic permeability of the core also increases slightly. Therefore, the error of the transformer increases with the increase of the secondary load, but less than a proportional increase.
