3 Phase Power Quality Analyzer
Basic Setup
37
Events
The Events list shows every type of event that might have occurred. These can be filtered into
event types such as dip, swell and interruption, waveshape deviation, transients, rapid voltage
changes, mains signaling, and inrush current. Each type of event can be selected for a closer
view by waveshape and RMS profile.
Flicker
The flicker values of Pinst, Pst, and Plt show for each phase:
P
inst
is instantaneous flicker that is calculated over a 200 ms period
P
st
is short term flicker calculated over a 10 minute period
P
lt
is calculated over a 2 hour period.
Unbalance
The Unbalance screen shows the complete range on unbalance variables for voltage and
current. These include positive, negative, and zero sequence values that are calculated in
accordance with IEC61000-4-30.
Scope
The Scope screen is a quick check of each voltage and current waveform for each phase that
resembles an eight-channel oscilloscope display.
Phasor
The Phasor screen hows the voltage and current phasors to indicate the relationship between
the phasors with relative or absolute angles.
Basic Setup
The basic settings are accessed with the settings button on the Home screen. This accesses
three group of setting, Instrument Settings, Communication Settings, and Tools.
Instrument Settings
Touch to open the Instrument Settings menu.
