2.4.1 PROTECTION ELEMENTS
Phase and ground units use as operation magnitude the current value received by the unit in current inputs, while the
neutral unit uses the calculated current value from the three phase currents.
The isolated ground unit will be used only for those applications where the neutral is completely isolated, and it uses the
fifth CT of the unit. This CT has a sensitivity that is 10 times higher than the universal model (connected to 1A or 5A
transformers). Therefore, it does not admit such a high permanent overload.
