The Webserver includes real-timecircuit information in bothnumeric and graphical visualformats to help monitorcircuit parameters such ascurrent loading, voltage andpower levels, power factor,THD, Flicker and more. TheWeb server also providesenergy and demand readingswith graphic usage plots tohelp analyze energy usagepatterns. Energy readingsinclude kWh, kVARh,delivered and received andkVAh with time of use andRTP displays. The intervalenergy usage plot includesthe ability to do week-toweekand month-to-monthenergy consumptiongraphical comparisons forbenchmarking purposes.Both the Power Xpert Meter4000/6000/8000 embeddedWeb server and the localgraphic display supportgraphical trend charts of keycircuit measurements suchas current, voltage, powerand energy. The trend chartsupports a zoom feature thatallows the user to view dataover a short period of 16hours up to 4 years. Thetrend chart includes zoom in/out buttons and a horizontalslider bar control to managescrolling forward and backwardthrough the data. Trend chartsof basic readings includeminimum, maximum andaverage readings. Trendcharts of interval by intervalenergy data also displaypeak demand.Note: For remote access andnetworking capabilities such asconnecting to a LAN/WAN, usethe optional CommunicationsExpansion Card (CEC).Sag/Swell/Transient Captureand Recording60 cycles of waveform areoversampled at 4096 samplesper cycle (Power Xpert Meter4000/6000), filtered throughanti-aliasing and recorded at512 samples per cycle andpost event data. The PowerXpert Meter 8000 samples ata rate of 100,000 samples percycle. Embedded Web serversupports viewing of triggeredwaveforms one channel at atime and includes the ability tozoom and to scroll horizontallyusing a slider bar.The Power Xpert Meter6000/8000 Series havepreconfigured (600 volts andbelow) trigger settings forsags, swells and transients,and do not require additionalsetup by the user. Waveformsare stored in non-volatile flashmemory using an industrystandard COMTRADEformat. Waveforms can beautomatically sent out asCOMTRADE attachments toan e-mail following an event,or can be retrieved from anFTP (File Transfer Protocol)directory structure inthe Power Xpert metermodule’s memory.Historical Trend LoggingThe Power Xpert Meter 4000/6000/8000 records historicaldata for graphical viewingfrom the Local display orthe embedded Web server.Graphical views of historicaldata support pan and zoom.145 standard meteringparameters are logged aspart of the standard meterfunctionality including min./max. and average for eachparameter. The averages arecalculated over the intervalperiod. The minimum andmaximum readings are basedon 200 ms calculations.Storage capacity for standardtrend plots includes all of thefollowing intervals:●●●●●Every 5 minutes for48 hours (2 days)Every 15 minutes for192 hours (4 days)Every hour for 28 days(4 weeks)Every 8 hours for56 weeksEvery week for 44 monthsNote: Trend plot data can beeasily exported to third-partyapplications, such as MicrosoftExcel in csv-file format.In addition, meteredparameters are automaticallystored on the built-in FTPServers, where they can beeasily copied and importedinto third-party applicationsfor benchmarking andanalysis. Logs on the FTPServer include the min./max.and average for 145 standardmetering parameters at5-minute intervals.Storage capacity fortrend data:●●6 days of 5-minuteinterval trend dataCapacity=18,144 intervalsEnergy Profile DataThe Power Xpert Meter 4000/6000/8000 records Real andReactive energy forward,reverse, net and absolutesum, as well as Apparentenergy (kVAH). Up to 8 statusinputs can be configured asenergy accumulators forcounting KYZ pulse inputs(option). These readings arestored over a configurableinterval from 1 to 60 minutes,as well as in daily andweekly totals.With the optional LAN/WANEthernet CommunicationExpansion Card (CEC), userscan easily configure themeters to send periodice-mails at user-definedintervals of energyconsumption and powerdemand. E-mails containa summary of readings perrate structures and also havethe actual measurementsattached to the E-mail’sbody as a CSV file in aZIP container.In addition, meteredparameters are automaticallystored on the built-in FTPServer, where they can beeasily copied and importedinto third-party applicationsfor benchmarking andanalysis. Logs on the FTPServer include energyconsumption logs, onefor every month in CSVfile format, trendedmeasurement logs alsoin CSV file format andwaveform captures inCOMTRADE file format.Storage capacity for energyprofile data:●●●●62 days of 15 minuteinterval energy and pulseinterval data.Fixed interval capacity= 5952 intervals.Configurable intervalsfrom 1 to 60 min372 days of 1 dayaccumulated energy andpulse interval data208 weeks of 1 weekaccumulated energyand pulse interval dataEnergy and DemandComparisonsEnergy and demand usagepatterns can be analyzed withthe month-to-month, weekto-weekcomparison chartbuilt into the meter.
