14.3.8 Voltage Events
·Any voltage event that violates the CBEMA / ITIC
power quality window will be captured and writ-
ten to the USB flash drive.
·A USB drive must be installed in the meter (no
larger than 32 GB) to capture events.
·The “nominal” L-L system voltage must be correct-
ly set on Configuration > General Setting Menu.
·Events can also be downloaded over the network
as a .csv file by selecting the „ Download Voltage
Events“ button.
·Events will be display on the local log and will dis-
play the time and date of occurrence (Timestamp),
Event Type (Line Voltage Swell, Line Voltage Sag,
Dropout, Low Frequency Decaying Ringwave,
High-Frequency Impulse and Ringwave).
·Events are also written to Modbus registers as
well as an event counter.
·Each event will be plotted by a single point in
the graph according to where the voltage event
occurred. Events can be cleared by selecting the
„
Remove“ button.
INFORMATION
