TEMA transducer
Accuracy and safety in measurement. A wide range of solutions for use with CTs.
Signal converter devices
Tema transducers are signal conversion devices used to measure voltage and current of the main electrical parameters. Solutions for installation on DIN35 rail or toroidal with integrated transducer are available.
These transducers are used for current measurement of the mean value of the true root mean square value (TRMS) even on systems with strong harmonic disturbances (Tema I4e only). Response time less/equal 300ms. (100ms for Theme I4e). The range consists of:
- Tema I: self-powered current transducer
- Tema I4: current transducer with programmable output
- Tema I4e: TRMS current transducer
They adapt the primary voltage values to the characteristics of the measurement or protection equipment, providing a proportionally reduced secondary voltage to the standard 100V values (other values on request). IME voltage transformers comply with the EN/IEC 61869-1, EN/IEC 61869-3 standards and, depending on the intended use, can be divided into:
- Measurement: Classes: 0.5-1 / Applications: counting and industrial measurements
- Accuracy: Class: 0.2 / Applications: counting and measurement with high degrees of reliability
- Protection: Class: 3P / Applications: combination with protection relays.
