Comment on the relationship between the number of turns and the ratio of the current transformer

- Dec 18, 2019-

It is known from the corresponding experiments that the ratio of the primary current to the secondary current is equal to the inverse ratio of the primary turns to the secondary turns ratio. That is to say, if the number of cores of this transformer is 1匝, its ratio is 500/5; the number of core turns is 2匝, the ratio becomes 250/5, the ratio of current transformer It changes with the change in the number of cores.

According to this relationship, we can also calculate the current of the current transformer to control the current through the current transformer, and the device is burnt out due to excessive current. It can be seen that this knowledge is very important. If it is well mastered, it can protect the current transformer.
