Technical Data
An Easy-Set function is also available with the visualization
software with which the parameterization can be performed
in accordance with the IEC standard.
Four relays are used to control 5 cooling stages. These can
also be selectively controlled during load changing operation.
This permits a time-equalized load of the individual cooling
stages. In addition one relay each is available for Alarm and
Trip. The switching point, the hysteresis and the delay time of
the individual relays can be set as desired and they can be
addressed via the oil or winding temperature. Manual
operation is also possible as an alternative.
A further special feature is the life management calculation
in accordance with the IEC or ANSI standard.
A temperature sensor can be connected to the 4-20mA sensor
input to record the ambient temperature. A Pt100 sensor must
then be used to detect the Top-Oil temperature.

The basic device indicates one oil and winding temperature
each on an LCD display. This requires the connection to the
device of a temperature sensor with Pt100 or 4…20mA
output which measures the „TopOil“ temperature in the
transformer. The minimum and maximum values of the oil
and winding temperature as well as the maximum value of
the load current are indicated and can be called later. Two
analog outputs and one RS 485 interface are available for
remote indication of the temperature values.
The data logging function is used to store the temperature-
specific data on the device at regular intervals so that it can
be called at all times.
The thermal image of the transformer is simulated in
accordance with IEC 60354 or ANSI standard. For this the CT
current which indicates the load of the transformer must be
connected to the device. Parameterization of the transformer
and cooling stage can be performed via the keys on the front
or via visualization software which is available as an option.
