Auto Correct is not available if the algorithm is not able to detect a
better phase map or when no errors are detected.
Note
It is not possible to detect all incorrect hook-ups automatically.
You must verify the suggested modifications carefully before
you apply the digital correction. Applications with single-
phase energy generation can deliver the wrong results when
you apply the Auto Correct feature.
In three-phase systems, the algorithm creates a sequence with a
clockwise phase rotation.
Correct Digitally
Push (Show Menu) and select Correct Digitally to access the
connection correction screen. This screen allows you to virtually swap
phases and invert the current inputs instead of a manual correction.
Phasor
The Phasor screen shows the phase relation between voltages and
currents in a vector diagram. Additional numerical values are RMS
and fundamental phase voltages, currents, and phase angles.
1.
Push (Show Menu) and select Phasor to access this
screen.
The reference channel with 0° is the voltage phase A/L1 in
Energy studies and the current channel A/L1 in Load studies.
2.
Push (Absolute Angles) to display the current phase
angles with their values in the three phase system.
3.
Push (Relative Angles) again to toggle the display and
show the current phase angles relative to the corresponding
voltage.
Power
– In the Power mode you can get the values and a live trend
chart for each phase (A, B, C or L1, L2, L3) and total as:
•
Active Power (P) in W
•
Apparent Power (S) in VA
•
Non-active Power (D) in var
•
Power Factor (PF)
Use (Fundamental/RMS) to toggle between full bandwidth
power values and power of the fundamental.
In the fundamental power screen you see these values:
•
Fundamental Active Power (P
fund
+) in W
•
Fundamental Apparent Power (S
fund
) in VA
•
Fundamental Reactive Power (Q
fund
) in var
•
Displacement Power Factor (DPF) / cosϕ
Push (Show Menu) to open a list of simplified Power screens
that show all phases and total of one parameter, all parameters of one
phase, or total.
