To set the secondary transformer voltage, proceed as follows:
1. Go to Settings > Parameters > Transformer data > Secondary trans-
former voltage .
2. Enter the secondary transformer voltage.
3. Press the Accept button to save the modified parameter.
Primary transformer current
You can use this parameter to set the primary current of the current trans-
former.
If you use the optional function "Hot-spot calculation on 3 different windings
(W1, W2, W3)", you must set the parameter for W1, W2 and W3 respec-
tively.
To set the primary transformer current, proceed as follows:
1. Go to Settings > Parameters > Transformer data > Primary trans-
former current .
2. Enter the primary transformer current.
3. Press the Accept button to save the modified parameter.
Secondary transformer current
You can use this parameter to set the secondary current of the current trans-
former. You can select the following options:
▪ 0.2 A
▪ 1 A
▪ 5 A
If you use the optional function "Hot-spot calculation on 3 different windings
(W1, W2, W3)", the setting of this parameter applies to all 3 windings.
To set the secondary transformer current, proceed as follows:
1. Go to Settings > Parameters > Transformer data > Secondary trans-
former current .
2. Select the secondary transformer current.
3. Press the Accept button to save the modified parameter.
Setting measurement mode
If you are measuring the voltage and current with the 3-phase UI 3 measur-
ing module, you can use this parameter to set whether you have connected
the voltage transformer between 2 phases or between a phase and neutral.
To set the measuring mode, proceed as follows:
1. Go to Settings > Parameters > Transformer data > Measuring mode .
2. Select the option you want.
3. Press the Accept button to save the modified parameter.
