3.4 - Configuration in customised
mode
3.4.1 - Useful data
To create a file for customised configuration,
you will need following data.
• Excitation:
- type,
- excitation current value at no load,
- excitation current value at full load,
- excitation current value on short circuit
3xIn,
- exciter resistance.
• Machine:
- machine rated power,
- rated voltage,
- frequency,
- power factor,
- PQ curve with the maximum power
absorbed.
• Regulation:
- values of voltage sensing PT,
- value of the droop CT,
- the possible additional configuration:
push button, diodes default, follower on
manual mode, etc.
3.4.2 - Creation of configuration file
On EasyReg®, go to « File » then « New customised configuration ».
A page, containing 2 tabs « Customised » and « Protections and limitations » appears:
all the
values need to be filled in order to let the configuration being taken into account.
