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.
