Signal
Meaning
Zero sequence unbalance
Ratio of zero sequence component to positive
sequence component in percent
Negative sequence unbalance
Ratio of negative sequence component to
positive sequence component in percent
Positive sequence component
Percentage of symmetrical voltage vectors
(*)
in
rotation direction
Angle of the positive sequence component
Phase shift of the positive sequence component
percentage of U1 compared to the reference
signal
Negative sequence component
Percentage of symmetrical voltage vectors,
against the rotation direction
Angle of the negative sequence component Phase shift of the negative sequence
component percentage of U1 compared to the
reference signal
Zero sequence component
Percentage of voltage vectors all showing in the
same direction
Angle of the zero sequence component
Direction of the zero sequence component of
the voltage vectors
(*)
The voltage vector is formed from the RMS value of the voltage (as vector length) and the
current phase (as vector angle).
Name
The names are set by default but can be edited. To allow an unambiguous identifi-
cation, they contain the input channel and the characteristic value. You can addi-
tionally assign two comments by clicking the
icon in the signal name field.
