WIBEEE C FLEX

Rogowski coils have some features that make them very different from standard current transformers. The most remarkable ones are that: 1.- The output they provide is in mV. 2.- They provide the proportional value of the current, but shifted 90º. 3.- They do not saturate. Hence, when we use a Rogowski coil in combination with a measuring or protection device, we need to place some electronics to integrate the signal and second we need to adapt the standard current input which traditionally has been …/1A or …/5A to support a 100mV signal. When these electronics and the power supply for running it are inside the measurement or protection device that is connected to the Rogowski, we talk about passive Rogowski coils, because the Rogowski itself does not need to have electronics on them and they do not need to have an external power supply. Our CFLEX Series of Rogowski coils, flexible CTs or flexible current sensors are ideal for retrofit or new installations, because they can be installed quickly and easily in any electrical installation, without the hassle of interrupting the electrical circuits. At the same time, they measure the AC current with a full rejection of the DC component, very low temperature dependence and an excellent linearity.
