12.14 Power Quality Measurement Capability

12.14 Power Quality Measurement Capability
The 1133A is equipped to detect power quality issues and record them to flash memory and/or
send them out one of the available ports (RS-232/485/Modem and Ethernet). Flash memory may
be configured to record types of information: (1) Revenue and (2) Event data. Revenue quantities
are recorded on a fixed schedule and may include many more items than a typical energy meter
would record. Event data are logged on the occurrence of an event trigger and designated to initiate
logging data. System status is used for advanced monitoring and control of the operation of the
1133A and system node to which it is connected.
Some of these power quality issues are specified below, and may be configured through
PSCSV Software to trigger as an event. Other Power Quality issues may be seen as Revenue
Information; this includes Energy, Voltage/Current, Frequency Variation, Flicker and Harmonics.
To configure through PSCSV software, see Chapter 7. Regularly check the Arbiter web site at
www.arbiter.com/pscsv/index.php for updates to PSCSV.
