TEMPERATURE MONITORING UNIT DTI AND EDTI
DTI and eDTI
Product description
The Temperature monitoring device DTI/eDTI is used in resin or dry type transfor-
mers and can also be easily adapted for use in oil transformers.
The DTI/eDTI uses PT100 temperature probes for a constant monitoring of tran-
sformer temperatures. The device generates two intervention levels of electric
signals (alarm and trip).
Safety notes on the equipment operation
The electrical installation must conform to the national safety regulations.
The Temperature monitoring device DTI/eDTI has double insulation. Earthing is
not required.
CAUTION
The wires must be fixed properly
The DTI family are devices which use PT100 temperature probes for constant
monitoring of transformer temperatures in 4 points: three on the transformer
winding columns and one on the machine's magnetic circuit.
If the transformer malfunctions, causing its temperature to rise, DTI unit genera-
tes an alarm signal. If the temperature reaches danger levels the unit generates a
second intervention level. Moreover, a switch can manage the fan.
Installation
The device must be installed and used by personal opportunely learned.
Before to proceed at the installation it's necessary to verify if the device is intact
and it hasn't damages due to transportation or handling. The power supply must
be compatible with the device range. The instrument installation must be done in
total absence of voltage and observing the security norm in force.
All operation of maintenance and reparation executed by not authorized persons
are forbidden.
If during the functioning the device becomes unsafe, it's necessary to put it out of
action and to be sure that this device won't be used unintentionally.
The use shall be considered unsafe when the instrument:
• doesn't work regularly
• has damage clearly visible
