Definition of Vn:
Vn is dependent on the
»Measuring Channel« setting in the current protection modules.
In case that this parameter is set to "Phase to Phase":
Vn
=
MainVT sec
In case that this parameter is set to "Phase to Neutral":
Vn
=
Main VT sec

If the parameter
»VT con« within the field parameters is set to »Phase to Phase« the setting
»Phase to Neutral« in the current modules is effectless.
