Metering Devices, Protective Relays, Software and Connectivity
Metering Devices
Energy Comparison
Energy usage patterns can be
effortlessly analyzed with the
month-to-month, week-to-
week comparison chart. Raw
data can be easily exported
with the “Save Table” option
to other applications such as
Excel for further analysis or
graphing (firmware version
12.x.x and higher only).
Note: All data logging for
trend plotting is automatically
preconfigured in all of the Power
Xpert Meter 4000/6000/8000
meters. In addition, the 6000
and 8000 Series meters have
sag, swell and transient triggers
built-in according to the ITIC
(CBEMA) standard.
Demand Comparison
Demand comparison
compares power
consumption day-to-day,
month-to-month or week-to-
week. Power Xpert Meters
can set to measure demand
at 1 to 60 minute intervals.
Both sliding and fixed interval
windows are supported for
maximum flexibility.
Disturbance Recording
Sag/Swell Recording
60 cycles of waveform are
recorded at 256 samples per
cycle including 30 cycles of
pre- and post-trigger data.
The Power Xpert Meter 4000/
6000/8000 embedded Web
server supports viewing of
triggered waveforms one
channel at a time including
the ability to zoom and to
scroll horizontally using a
slider bar. Waveforms are
stored in Power Xpert
Meter’s 4000/6000/8000
non-volatile flash memory
using an industry standard
Comtrade format.
Waveforms can be
automatically sent out by
e-mail following an event,
or can be retrieved from an
FTP directory structure in the
meter module’s memory.
ITIC Analysis Plot
(Power Xpert Meter 6000/8000)
The ITIC Web page includes
counters to track the
occurrence of disturbances
and a pass/fail summary.
In addition, selecting any
disturbance counter links to
a detailed event view of the
disturbances in that ITIC
category. Disturbance
waveforms can be viewed
from the browser.
Events Calendar
(Power Xpert 6000/8000)
The Events Timeline calendar
view provides instant insight
to the frequency of power
events and helps detect
reoccurring problems. Color-
coded events can be filtered
to detect specific issues.
Configuration Page
Web Server Device
Configuration
Special software is not
required to configure a Power
Xpert Meter 4000/6000/8000.
The embedded Web server
includes comprehensive
device set-up capability.
Discrete Contact Inputs
The optional PXIO-B
expansion card offers 8 digital
inputs that are useful for a
variety of applications such as:
●
Status indication with time
stamping of transitions
(1 ms precision).
●
Pulse counting of KYZ or
other utility pulses such
as air, water or gas.
●
High-speed triggering of
waveforms based on
events such as breaker
trips or static transfers
●
Demand interval timing
taken from a master utility
meter end of interval pulse
Status inputs are self sourced
providing a nominal 24 Vdc
(20–30 Vdc) across the circuit.
Names can be configured for
each input for ease of use.
Relay Outputs
The optional PXIO-B card
includes three 5A form C
relay outputs rated for
240 Vac or 30 Vdc. These
outputs can be used for
applications such as:
●
Alarm annunciation
●
KYZ pulse output
Alarm outputs can be driven
from triggers based on
metering values. Output
modes include:
●
Normal—relay energized
during alarm condition
●
Latched—relay energized
by event trigger,
de-energized by
acknowledgement
●
Timed—relay energized by
event trigger, maintained
for a programmed interval.
Communications Expansion
Card (CEC)
The optional CEC Card offers
two Ethernet connection
options, 10/100Base-T and
a fiber-optic port that can
be used for the following
applications:
●
Monitoring, managing and
configuring the meter
remotely using a standard
Web browser interface like
Microsoft Internet Explorer
●
Alarm notifications via
e-mail, SMTP
●
Enabling access to the
meter’s FTP server
(energy, trend and
waveform logs)
●
Providing Modbus TCP/IP
or RTU communications
to BMS systems
●
Providing DNP 3.0 over
Ethernet to utility systems
●
Providing SNMP
communications to
NMS systems
●
Synchronizing with an
NTP server for 1ms
timestamping resolution
●
Asset management
via SNMP to Network
Management Systems
●
Updating firmware on
the meter
