■ 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.
