CTT-8

   CTT-8

DEVICES FOR PROTECTION, CONTROL, THERMIC MONITORING OF TRANSFORMERS,
MOTORS, GENERATORS, INDUSTRIAL APPLICATIONS

 

Programmable thermal control unit up to 8 inputs from Rtd Pt100 sensors.

• Programmable alarm, trip and ventilation threshold on each input

• It shows the parameters and measures on 2 ample digital displays, added function of maximum values memory, it displays automatically the highest temp

• Extendend range of power supply 20 ÷ 250 Vcc/cc or 110 - 230 - 400 Vca

• Serial output RS232/RS485 Modbus Rtu with management software

• Analog output 0/4 ÷ 20 mA measures conversion

 

FUNCTIONS

The control unit programmed through keys located on the front panel:

• Election of the number of active channel

• Ventilation control

• Alarm and trip temperatures (hold function)

• Storage of alarm abd trip conditions

 

APPLICATIONS

Overtemperatures caused by overloads or internal failure due to degradetion of the dielectric qualities of insulating materials in transformers and electrical machines, inevitably leads to a reduced efficiency andenergy loss in ditribution systems. To prevent and control degradation ofinsultaing materials in electrical machines due the thermal stress, it sinecessary to use integrated measurement systems such as CTT control units.
