22.3Metering Devices, Protective Relays, Software and ConnectivityMetering Devices222222222222222222222222222222222222222222222222222222222222ITIC Analysis PlotThe Power Xpert Metergraphic display (option) andWeb server include a graphicrepresentation of the ITICplot (Power Xpert Meter6000/8000) with counts ofdisturbances and transientsthat have occurred. The ITICplot organizes events into8 distinct disturbance zonescorresponding to severity anda 9th zone for transients. Apass/fail count is displayedto indicate how many eventsare outside the ITIC limits.Clicking on any counter in theITIC Web page will link theuser to the event view anddisplay all triggered events inthe selected zone. ThisStorage Capacitymakes it simple to viewdisturbance waveformsassociated with the ITIC plot.A separate ITIC graph isavailable to review individualITIC events. This graph willshow the user the eventhit position on the graphand the event durationand magnitude.Inputs and OutputsPower Xpert Meter 4000/6000/8000 is available withan optional digital I/O card,which includes:●Eight digital inputs—self sourced 24 Vdc●Three relay outputs—5 A max. continuous,240 Vac max., 30 Vdc max●Two solid-state outputs—80 mA max. continuous,30 Vdc maxEach of the 8 inputs areinterrupt driven, allowingfor 1 ms accuracy of digitalevents time stamps (1 msaccuracy requires local NTPTimeServer). Inputs can alsobe configured for demandsynch and pulse counting.Inputs selected for pulsecounting can be scaled.Interval by interval pulserecordings are maintained inprofile memory and can bedisplayed graphically. Outputscan be used for KYZ, or alarmannunciation.Ratings●Application to 500 kV,no PTs to 600V●CT ratios selectable fromstandard 120/600 Vac line●CT inputs accept 5Asecondary● Power supply:● Standard 120/240 Vacor 110/250 Vdc●Low voltage 24–48 Vdc(contact Eaton foravailability)Power Xpert Meter 4000/6000/8000 Estimated Memory and Storage Capacity with 2/4/8 GB Memory CapacityModel Memory Event File Size (KB) Typical Severe Typical Severe Typical SeverePXM4000 2 GB Subcycle Disturbance 1260 10 60 12.3 73.8 166 28PXM6000 4 GB ITIC Event 1260 5 20 6.2 24.6 666 166Subcycle Disturbance 1260 10 60 12.3 73.8 333 55ITIC + Subcycle Disturbance Total---> 15 80 18.5 98.4 222 42PXM8000 8 GB ITIC Event 1260 5 20 6.2 24.6 1332 333Subcycle Disturbance 1260 10 60 12.3 73.8 666 111Transients 2048 3 30 6.0 60.0 1365 137ITIC + Subcycle Disturbance + Transients Total---> 18 110 24.5 158.4 335 52NotesThe typical and server power quality event occurrences are estimates and may vary depending on the electrical environment.Memory is not allocated by event category; memory is used first come, first served.Occurrence Per Month Memory Usage (MB) Months of Capacity 190 Volume 3—Power Distribution and Control Assemblies CA08100004E—December 2010 www.eaton.com
