Current transformer TI-100-02S
100/5 transformer. 2,5 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.
Operation
The conductor with the current to be measured passes through the main bore 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 - measured secondary current; IPm - measured primary current.
Сechу of the device
- Proportional change of high intensities to low intensities.
- Adapted to the measurement ranges of control and measuring devices.
