Abstract
PURPOSE: To facilitate the switching of a current transformation ratio, by connecting the winding end terminal of a current transformer to the tap of another current transformer and leading out the winding start terminal of the last current transformer, the tap of the first currnet transformer and the winding end terminal of the last transformer.
CONSTITUTION: A terminal 1l of the secondary winding 3 of a current transformer CT1 is connected to a terminal 2K2 of the secondary winding 3' of another currnet transformer CT2. Other terminals 2K1, 2l of the secondary winding 3' of the current transformer CT2 and another terminal 2K2 of the secondary winding 3 of the current transformer CT1 are led out as a winding start terminal K1, a winding end terminal l and a tap k2. When the currnet transformers CT1, CT2 with a current transformation ratio of 200W100/5A are used at 200/5A, a load Zb is connected between the terminals k1, l. This is equivalent to the case that only the current transformer CT2 is used. At that time, two times of a rated load can be carried by the single current transformer. When the current transformers CT1, CT2 are used at 100/5A, the load Zb is connected between the terminals k2, l. At that time, the current transformers are coupled in series with each other and two times of the rated load can be carried.
