Overtemperatures caused by overloads or internal failure of transformers and electrical machines, inevitably leads to a reduced efficiency and energy loss in ditribution systems.

To prevent and control degradation of insultaing materials in electrical machines due the thermal stress, it is necessary to use integrated measurement systems such as CTT control units.

CTT control units are able read four temperature values (8 values on model CTT-8) with help of four Pt100 probes. For each inputs it is possibile to set the threshould temperature of alarm and trip with great accurancy and to display the maximum values reached

CTT control units can be supplied with the serial interface to allow remote monitoring of temperatures using a PC.
