CTG210 Carlo Gavazzi

CTG210, Differential Current Transformers, CTG210, CTG is a family of "differential current transformers". These devices detect the difference in the intensity flow of conductors passing through the coil and work in single-phase or three-phase systems. When the vector sum of the current flowing in the direction of the load and in the neutral wire (if present) is different from "0" (zero), an intensity is generated in the secondary of the CTG transformer. This difference in currents is normally caused by a leakage current that can pose a hazard. The output signal can be used by a differential protection relay that disconnects the monitored load or sends an alarm signal., CTG210, CTG transformers are used to detect potentially dangerous leakage currents in electrical charges. Usually in electric motors, pumps or devices installed in metal structures. They are approved to be used in combination with the DEA71 and DB71 differential protection relays CARLO GAVAZZI.
