harmonics relative to the individual limit defined by the
standard defined in the measurement configuration. Each
bar is green when the measurement is below the individual
limit for this harmonic or THD. When the standard defines
two limits, for example, a limit for 95 % of all values and a
limit for 99 % of all limits, the bar turns orange when the
measurement values comply with the 99 % limit but violate
the 95 % limit. When both limits are violated the bar turns
red. When the standard defines only one limit for each
harmonic or THD, the bar turns from green to red when
this limit is violated. The number of displayed harmonics
varies in accordance with the selected standard.
The side menu in the harmonics screens has dual use.
First, select the parameter to display and confirm with .
The selector bar jumps to the lower section for the phase
selection. The number of available phases and the Neutral
current depends on the selected topology. Refer to
Measurement Configuration for details. Make your choice
and confirm again with .
Some screens do not include  (Show Menu) to
access the side menu. Use the cursor keys instead.
Events
The Logger captures events on voltage and current. The
events are shown in a table with the columns ID, Start
Time, End Time, Duration, Event Type, Extreme Value,
Severity, and Phase. Touch the arrows left and right of the
table to view all available columns. Use  to highlight
an event of interest. On the 1738 or the 1736 with
1736/Upgrade license, use  (Waveshape) and 
(RMS Profile) to review the recordings triggered with the
start of the event.
The voltage events are classified in dips, swells, and
interruptions and are measured according to the standard
IEC 61000–4–30 "Electromagnetic compatibility (EMC) -
Part 4-30: Testing and measurement techniques - Power
quality measurement methods". According to this standard
the Logger applies the polyphase event detection on split
phase and three phase systems with the exception of the
topologies 3-phase Delta balanced and the 3-phase Wye
balanced. The events are captured and reported for phase
A/L1 only.
The polyphase event detection simplifies the event
table because events on multiple phases are
combined when they occur at the same time or
overlap. In the Energy Analyze Plus software you
can select to get either a table with combined
events using the polyphase event detection or a
table with events for each individual phase in order
to review details, like start time, end time, or the
extreme value on an individual phase of interest.
