dilo current transformer solution

dilo current transformer solution

It is known that the value of transformation ratio (actual ratio) is not equal to the turns ratio in current transformers.Also, the value is not constant but depends upon the magnetizing and loss components of the exciting current, the secondary winding load current and its power factor.This means that the secondary winding current is not a constant fraction of the primary winding current but ...
