Current transformers proportionally change large currents to lower values, adapted to the measuring ranges of control and measuring devices.

Operation of the TO-1600 single-phase open-core current transformer

The conductor with the current to be measured passes through the main opening of the transformer (P1/P2), which is equivalent to one winding of the primary winding. The terminals of the secondary winding S1 and S2 are connected to the terminals of the measuring circuit of the control or measuring device.
The ratio of the currents in the two windings is a constant quantity and is called the current ratio: IPn/ISn=N, where IPn is the rated primary current; ISn is the rated secondary current; N is the gear value. From the value of the current flowing through the secondary winding, the value of the current flowing through the primary winding can be determined : ISm*N=IPm, where ISm - secondary measured current; IPm - primary measured current.

Caution!
It is recommended to connect the secondary system with a wire of not less than 2.5 mm² in diameter.
Recommended earthing of terminal S2.
It is forbidden to disconnect the secondary circuit during operation of the transformer (possibility of high voltage resulting in paralysis of persons or damage to the equipment).
