▪ Display of the winding temperature.
▪ Pointer thermometer with adjustable micro-switches.
▪ The displayed temperature corresponds to the winding temperature based
on the oil temperature, secondary transformer current and the tempera-
ture difference.
▪ The secondary transformer current supplies a heating resistor in the me-
chanical pointer thermometer with power, thus causing a temperature in-
crease that corresponds to the loading of the transformer, as compared to
the actual oil temperature that was measured.
TT version
The pointer thermometer is equipped with a signal converter that depicts the
temperature value as an electrical signal (4...20mA). Read chapter Con-
necting the analog sensor (optional/TT version) [►Section 5.4.7, Page 59]
to connect the sensor.
