PHASOR screen.
Shows phase relation between voltages and currents in a
vector diagram. An example is the Scope Phasor screen:
1
3
2
Screen information:
c
RMS values of the waveforms are
displayed in the header.
d
Vector diagram. The vector of the
reference phase A (L1) points to the
positive X-direction.
e
Additional data such as fundamental
phase voltages, frequency, and phase
angles.
Function keys:
F1
Selection of data set to be displayed.
F3
Return to Scope Waveform screen.
F5
Switches between HOLD and RUN.
BAR GRAPH screen.
An example is the bar graph screen for Power Quality
Monitoring. This screen gives a quick indication if
important Power Quality parameters meet requirements.
Parameters include RMS voltages, Harmonics, Flicker,
Rapid voltage changes, Dips, Swells, Interruptions,
Unbalance, and Frequency.
The length of a bar increases if the related parameter is
further away from its nominal value.
The bar graphs have a wide base (indicating a user
definable percentage of the time that a parameter must
be within specified levels: for instance 95 % of the
readings over 10-minute observation periods must be
within level) and a narrow top indicating the fixed 100%
limit. If one of these limits is violated, the related bar
changes from green to red. Dotted horizontal lines
indicate both limits on the display.
