Current transformer TO-1000

TO-16000-5, 5902431675442

With open core. 1000/5 transformer. 5 VA.
The current transformer is used for proportional change of high current strength to lower values, adapted to the measuring range of control and measuring devices.

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

Please note!
It is recommended to connect the secondary circuit by a wire with diameter of not less than 2.5 mm².
It is recommended to ground the S2 terminal.
It is prohibited to disconnect the secondary circuit during operation of the transformer (the high voltage that may appear pose a risk of electric shock to the people or damage to the device).
