MENU TRAFO
The menu TRAFO is used to configure the Transformer parameters at Mastertemp and have the following
parameters:
Temperature Gradient
Time Constant
Hot Spot Factor
Cooling Type
Nominal Current
Current Relation
To access the menu TRAFO, with the display in presentation mode and press key SET, the display will show the
tabs. Use the key ►, navigate to the menu TRAFO and press SET.
This menu have a password and shows a password reminder. Below is
0000
. Use the keys ▲▼ to type the
password and and the key SET to confirm and enter the menu. Case the password is wrong, it will show a message
WRONG PASSWORD and will return to
0000
.
After input the password, the
MasterTemp
TM
will ask it again only when going back to the presentation mode. In
case of continuing on the configuration in other menus, the password will not be requested again.
Originally, the Mastertemp password is 0000. In case of lost or forgetting, get in touch with Electron do Brasil and inform the
Password Reminder.
Navigate by menus, submenus and paratemeters with keys ▲▼◄►. Select the submenu or parameter and press
SET, change the variable with keys ▲▼ and press SET to confirm the changing. If exiting the parameter or submenu
without confirming, the parameters return to previous values.

OWG 1
OWG 2
OWG 3
0.1 to 100 °C
Configuration of the temperature gradiente of the windings.
This means the temperature difference between oil and the
avarage temperature of a winding after the thermal
stabilization in nominal load conditions.
OWG 1 –
Winding 1 temperature gradient
OWG 2 –
Winding 2 temperature gradient
OWG 3 –
Winding 3 temperature gradient
Time
Constant
TCW 1
TCW 2
TCW 3
0 to 500 s
Configuration of the windings constant of time for the thermal
inertia (seconds). This value is obtained in transformer heating
test. If this information is not available, use the value 300 s
(used for windings in copper).
TCW 1 –
winding 1 constant of time for thermal
inertia
TCW 2 –
winding 2 constant of time for thermal
inertia
TCW 3 –
winding 3 constant of time for thermal
inertia
