What is ASY
The ASY variable allows to control the symmetry of the star /
delta voltages (for systems without neutrals) and star voltages
(for systems with neutral). The variable is calculated as fol-
lows:
where the first formula is to be applied with delta systems,
while the minimum value calculated between the two is to be
used for the star systems.
It’s very important, as a general rule, to plug in
and extract the optional modules only when the
instrument is switched off.
