Voltage and current wave forms L2 line
In the “L2 Phase V-C” page are showed the voltage and current wave forms
with their peak values and crest factors. The wave form of the current has
the lower amplitude.
Voltage and current wave forms L3 line
In the “L3 Phase V-C” page are showed the voltage and current wave forms
with their peak values and crest factors. The wave form of the current has
the lower amplitude.
Variable reading of phase voltage
•
(V - kV) rms voltage between L1 and L2 [V
1-2
]
•
(V - kV) rms voltage between L2 and L3 [V
2-3
]
•
(V - kV) rms voltage between L3 and L1 [V
3-1
]
•
percentage of unbalance phase voltage [V

Note: the unbalance voltage appears only if it’s defined in setup.
Variable reading of line voltage
•
(V - kV) rms voltage L1 [V

•
(V - kV) rms voltage L3 [V

Note: the unbalance voltage appears only if it’s defined in setup.
Variable reading of line current
•
(A - kA) rms current L1 [I
1
]
•
(A - kA) rms current L2 [I
2
]
•
(A - kA) rms current L3 [I

]
Note: At the bottom of the page it’s showed the maximum of phases and
neutral currents (relative or absolute depending of the enabling of MINMAX
in the STORAGE menu).
Note: In the right side of the page the currents are graphical showed as a
percentage of full scale (5A or 1A). (1 = 100%, 1.2 = 120%).
