VMU-C Instruction manual 12
Value of the line voltages for the system
and for the star voltages (phase1n, phase2n
and phase3n). These values concern the
reference instrument (real or virtual). If the
reference instrument is virtual, each voltage
value shown to the side is calculated as the
average of all the relevant voltages of the
real instruments set as contributors.
Example:
LLsys Voltage = [VLLsys(st1)+VLLsys(st2)+VLLsys(st3)+VLLsys(st..)]/n
L1N Voltage = [VL1N(st1)+VL1N(st2)+VL1N(st3)+VL1N(st...)]/n
L2N Voltage = [VL2N(st1)+VL2N(st2)+VL2N(st3)+VL2N(st...)]/n
L3N Voltage = [VLN3(st1)+VLN3(st2)+VLN3(st3)+VLN3(st...)]/n
Where LLsys, L1N, L2N and L3N Voltage represent the values displayed in the green
frame. L1N(st1) represents the phase1-neutral voltage of instrument 1 , L2N(st2) the
phase2-neutral voltage of instrument 2, L3N(st3) represents the phase3-neutral voltage of
instrument 3 and so on … “
n
” represents the amount of instruments set as “
contribution
”.

Values of the star voltages for the reference instrument (lower orange
frame). In this frame data are continuously updated.
Current value for each phase. These values
concern the reference instrument (real or
virtual).

Main Menu:
this area displays the selected variables in graphic form. The type
of chart/displayed variables can change according to the selected icon (see
navigation menu) and to the variable the user wishes to display. In the bottom
section, besides, there is a frame displaying some information about the plant
(name, location,
…).
