Based on the equivalent schematic diagram of the current transformer, discuss the basic principles and characteristics of the two current transformer ratio inspection methods (current method and working voltage method), and strongly recommend a simple and reliable current transformer ratio Check the field experiment method-working voltage method.

The on-site transformation ratio inspection experiment during the work handover of the current transformer and after the winding is removed has been included in the key experimental new items.

Although the accuracy of the transformation ratio of the current transformer should be ensured by the manufacturing unit, for various reasons, it can occasionally be checked out incorrectly during field experiments (most of which are tapped errors).

Therefore, the on-site transformation ratio inspection experiment of the current transformer has become a new project that will not change for many years.
