What is ASY
The ASY variable allows the user to control the symmetry
of the delta voltages (for systems without neutral) and star
voltages (for systems with neutral). The variable is calculat-
ed according to the following formula:
Where: Vmax is the max. value among VL1-N, VL2-N, VL3-N
Vmin is the min. value among VL1-N, VL2-N, VL3-N
Vavg is the average: (VL1-N, VL2-N, VL3-N)/3
The variable is not displayed by the instrument, but it can be
retransmitted by the analogue or RS422 / 485 output and
can be controlled by means of the alarm.
