Summary
The Summary section compares the key power quality parameters to pre-defined levels.
It consists of three elements: Overview, Events and Harmonics.
The overview summarizes the overall power quality for the chosen reporting period in six
classes: frequency, voltage variations, voltage harmonics, unbalance, flicker and events.
The total number of readings for each of these variables is compared to the 100% limits. A
different percentage of the total number of readings (typically 95%) is also compared to specific
limits. This allows a power quality survey according to international or local standards (e.g.
EN50160).
The summary indicates the number of values within the limit and the extreme value measured
during the selected period.

Events
The Events section is a summary of the voltage and current events that occurred at this
location during the monitor period.
Events are defined as changes in the monitored voltage or current. These changes may be
subtle or severe.
Tolerance curves provide a graphical representation of the likelihood of an event to disrupt
equipment operations. Tolerance curves classify the event by magnitude and duration;
there are standardized tolerance curves for voltage such as CBEMA or ITIC and for current,
circuit breaker manufacturers supply curves of their equipments operation.

Harmonics/
Interharmonics
This section contains the voltage and current harmonics acquired during the monitor period.
Harmonics may be represented in summary showing the overall harmonics in a spectral format
or individual harmonics may be graphed over time to indicate the effects of harmonics and
particular loads switching on.
Harmonics are typically caused by switching electronic loads. The distortion caused by
harmonics can cause overheating in conductors and equipment and may cause equipment
malfunctions.

Total Harmonic Distortion (THD) /
Unbalance
This section contains summaries of THD for voltage and current.
Additionally graphical summaries of voltage and current unbalanced are displayed during the
monitor interval.
There are international standards recommending the allowable level of harmonic distortion, the
levels vary depending on the operating voltage level, it is recommended that you consult the
local prevailing standard for comparison with the levels found in this report.
Excessive voltage unbalance is an indication that one or two phases may be overloaded. A
redistribution of the loads on one or more of the phases may be in order.
Excessive current unbalance also indicates a poor distribution of loads. Although there may be
no corresponding voltage unbalance, excessive current unbalance may result in tripped circuit
breakers or transformer overheating.

Flicker
The Flicker section shows the effects of large fluctuating loads.
The standard flicker variables PST (short term, 10 minute value) and PLT (long term, 120
minute value) are graphed.
Flicker is a statistical measurement relating to the effect of fluctuating loads on lighting and
other sensitive equipment.
The typical sources of flicker are steel mills using large electric motors or arc furnaces on a
distribution network, or frequent starting of an elevator motor in an office building, or if a rural
residence has a large water pump starting regularly on a long feeder system.
