What is ASY
The ASY variable allows the user to control the symmetry of
the delta voltages (for systems without neutral) and star volt-
ages (for systems with neutral). The variable is calculated
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 can be
retransmitted by the analogue or RS422 / 485 output and
can be controlled by means of the alarm.
