Current transformers (CT)
They adjust the primary current values to the characteristics of the measurement or protection equipment, providing a proportionally reduced secondary current to the standard 5A or 1A values. IME current transformers comply with the EN/IEC 61869-1, EN/IEC 61869-2 standards and, depending on the intended use, can be divided into:
- Measurement: Classes: 0.5-1-3 / Applications: counting and industrial measurements
- Accuracy: Classes: 0.2-0.2s-0.5s / Applications: counting and measurement with high degrees of reliability even at minimum currents (1%In with 0.2s or 0.5s classes)
- Protection: Classes: 5P5-5P10-5P15-5P20 / Applications: combination with protection relays
