3-Phase Power Monitoring

Hello,
I am planning to measure the Power consumption in a building which has a 3-Phase voltage system. Each line is 220V. I am interested in measuring real time kVA, monitor it with Labview through a data acqusition module. I will measure separately the Amps of each phase as well and i will calculate from that the Power Factor for more accurate power measurement. Do you have any suggestions on what voltage/current clamps should i use? These clamps should give reference voltages in the range that the usb NI modules vould monitor. Please also give me your opinion if the thinking of this project is right. Any other better solutions?
Thank you,
CK

Have you thought about using the power meter PM870 from Square D (now is Schneider Electric)?

  • Three-Phase Power Analyzer, Etc.

    Hi All,
    I'm not sure if this is the right board for this question, or if I should ask it on one of the hardware boards.  Let me know if I should move it, please.
    I need to set up a LabVIEW-based system to monitor the following:
    1.  Output from three-phase power analyzer (480VAC, 0-100AAC) - this could involved monitoring formatted power-quality data from a power analyzer OR monitoring voltage and current on all phases, then doing the power quality calcs in LabVIEW
    2.  DC output current (0-200ADC) - This needs to be relatively fast (2000 samples/sec), but not very precise (0.1A resolution would be fine).
    3.  DC output voltage (0-600VDC) - Again, this needs to be fast but not very precise.  See current specs, above.
    4.  CAN bus - I'll be monitoring a CAN bus and processing CAN data, probably using an NI USB-8473.  I have much of the CAN code written already.
    Any suggestions on how I should proceed?  Has anyone had good results with specific power analyzers tied into an NI-based system?  What about current probes?  High voltage meters?  Is there any pre-written LabVIEW code for three-phase power analysis?
    Many thanks in advance.

    Hmm... I have used a few three phase power analyzers from Voltech, Valhalla, and Yokogawa with LabView.
    Right now I would say Yokogawa has my vote. Either the WT230 or (if you got the budget) a WT500. I am currently using both and find the Yokogawa supplied LabView vi's complete and full featured. Since neither of these can measure 100 amps directly you will need to use external current transformers. For best results I recommend buying matching current clamps from Yokogawa when you buy the analyzer Their use is pretty straight forward just enter the scaling factor into the instrument and the readings will be ranged correctly.
    DC current and voltage that high will require a current shunt and some scaling for your voltage. Then you could measure it with any decent DAQ device, maybe a cheap as a NI-USB6009. We like to use the Agilent 34970A with a 34901A multiplexer card for this application. The 34970A/34901A is our Engineering Lab workhouse it has the benefit of ISOLATED CHANNELS direct measurement of 300VAC/DC and it can read thermocouples.

  • How much phases power supply does the 875P Neo FIS2R got ??

    How much phases power supply does the 875P Neo FIS2R got  ?(
    And will it be enough for the Prescott  ?(

    Prescott will be made on a 0.09u process so it should use less power per MHz, I wouldn't worry about that.
    According to what I see it has 6 power regulators which usually means 3 phase.

  • Drive LEDs on 8-bit Digital I/O for WattsView Power Monitor

    Hi could someone please help me with modifying the following LabVIEW program: 
    About the program: 
    I'm currently building a bike generator that would have the ability to power LEDs (based on whatever power is output). The LEDs would look like it's scrolling. While doing some testing, it appeared that the maximum power obtained while pedalling the bike was about 3 W. Connected to the generator is a serial power monitor called WattsView, which is a circuit that contains a loop that measures amps using the hall effect. This circuit collects data of volts and amps, sends it the software it went with onto the computer, and I am also able to view power (calculated).
    On the WattsView circuit, an 8-bit Digital I/O is also included, which operates from 0 to 5 Volts DC. Below is a picture of how WattsView looks like. On the WattsView website, a free LabVIEW driver is also included. Below is also a screenshot of the program. 
    WattsView Website: http://wattsview.com/
    I currently do not have access to LabVIEW (it's on my work computer), so I will post other screenshots later. However, below is a table of what I would like to do with the 8-Bit Digital IO Port. 
    Basically, I would like to have each LED turn on when it reaches +0.3 W. Currently, my idea of doing it would be to create a constant from the power indicator of the LabVIEW program. I will then use the In Range & Coerce Function to set the upper and lower limits for the power range (using the power constants). 
    Upper limit: 0 W
    Lower limit: 2.4 W
    The In Range output will then be connected to the selector terminal of the case structure. So when: 
    In Range Output = 1: Execute equation to turn on necessary LEDs  
    In Range Output = 0: Do nothing 
    At this point, I have no idea where to go, particularly with the case for when In Range Output = 1. I was thinking of doing a bunch of nested case structures within this case for the different ranges. However, I don't know how I would do it so that the LEDs would scroll up when power increases, and scrolls down when power decreases. Any light of this situation? Any tips or advice is greatly appreciated. 
    Thank you for taking the time to look at my post! 

    I'm still confused on how to obtain power in the correct format. 
    Below is a screenshot of the entire LabVIEW WattsView Driver (Block Diagram) 
    Circled in red is the data of volts and amps that is being collected from the WattsView circuit connected to the generator. Double clicking this icon for "4 Mat Data" opens the following Front Panel:
    I opened the block diagram for this VI, and below is how it looked liked. Circuled in red, I determind this is where the output of power is, for P = V*I. Therefore, I created an indicator for the power to display the values on this VIs Front Panel. 
    I copied the Power indicator onto the main LabVIEW Driver Program, and below is how it now looks like: 
    I am unable to connect the Power indicator to the input of the Quotient and Remainder Function. This function accepts a double 64-bit, which is the data type of the Power indicator. Now I'm lost. How do I make this Power as the proper input into this function? And how would I go about inputting a constant valu of 0.3 into the second input of the function? 

  • 3 or 4 Phase power?

    does anyone know whether they use 3 or 4 phase power on the k8n neo?
    usually they state it in reviews, but i can't seem to find it mentioned at all anywhere.
    can anyone relay anything about this? ta.

    You can try to clear CMOS and try out with another video card.

  • BIOS - "EliteBooks" - what the HECK is "Power Monitor Circuit"?

    "PowerMonitorCircuit" setting in BIOS in EliteBook 8540W or most others:
    Dear HP Experts,
    Good job of obliterataing information on what it does, even a degreed engineer as myself is unable to decide whether to keep enabled or disabled in BIOS!
    Can you please tell what it does?
    NOT whether I should enable/disable - that I decide myself, just please:
    Explain its function.  Already read your "Service Manual" - but no word, all it says is setting name "PowerMonitorCirc", but not what it does !

    BEFORE YOU SPEAK, GET FACTS Mr. "Professor".
    FACTS:
    1) My Posting date - was a special "HP Experts Day" when their employees conducted 24-hour session, monitoring Forums & answering as officials, rather than as "user-to-user" forum.
    Perhaps you weren't aware 21-22 (?) September was that day.
    2) Previously offered answer was a vague finding from another user, which while afraid to appear "pedantic", is not a 100% clear explanation of what Circuit does.
    It's true I accept it for now as a somehwhat useful hint, but HP employees did not catch my question and not officially acknowledged that it's time to add info into Service + User's manual(s) [simply tell what this setting does].
    E.g. nobody needs an explanation what "Fan Always ON while on AC" setting in BIOS - things like that are selfexplanatory to anyone who's not a moron, BUT:
    But "Power Monitor Circuit" - at least they could care to add an explanation!
    I am one of those who is "particular" with his Soft/Firm/Hardware settings, and I like everything be perfect.
    That's Engineer in me.
    I need to know settings clearly, not some vague suggestion from another user.
    So I hoped for HP folks to live up to their promise on 22 September "Experts Day" to jump in to provide answers.
    Perhaps they got overwhlemed as I've noticed NUMEROUS other people postings that day along with me.

  • USB 6008_Lab View Power Monitor

    Hi,
    I'm doing a project on Power Monitoring Unit. Here I measure the line voltage and current and display it in the computer using the NI USB 6008 unit.
    So I'm giving two signals corresponds to the line voltage and current. Then use Lab View to calculate the power and power factor.
    I bought the USB 6008 unit and finding it difficult connect this hard ware to the Lab View software. I need to use the Lab view, not signal express.
    If you guys can give me a solution for this, it's greatly appreciated,
    Cheers,
    Milinda

    Hi,
    There is another problem that came to me when calculating the Power Factor.
    NI USB 6008 measures voltage inputs only.
    So, when I calculate the power, I have to measure Voltage and the line current.
    For the Voltage input signal, I can use a small transformer to step down the Voltage to an acceptable range with the DAQ. (230 V to 6V)
    For the Current input signal, 1) I can use a shunt resistor and measure the voltage difference across it and input it to the DAQ
                                          or 2) I can use the small Current Transformer and a burden resistor get a voltage difference across the burden
                                                   Resistor and input it to the DAQ.
    If i measure the power of a resistive load, Voltage and Current signal will overlap and gives no difference.
    If i measure the power of an inductive or capacitive load, there is a lag or lead between Voltage and Current signal.
    My question is, when it's an inductive load, which current input method will display the difference between voltage and current signal?
    Note: Power Factor - Angle difference between Voltage and current signal.
    Cheers,
    Milinda

  • Power monitoring utility

    Hi
    Is there a way to monitor, the comsumption of an external device.
    The reason I am asking, is because I just bough a small icybox (ib 250UE) and installed a 250GB in it.
    It works great str8 out of the box, and my PB supply its power through the firewire, or USB or combined together.
    I believe there is some issues regarding pulling power through the connectors of a PB and would not like to strain.
    Is there any utility, that could allow me to monitor, how much power is drained from the PB by the external HD.
    Thanks

    visit iSlayer and get their iStat Pro (actually, u can find it here in the osx downloads, widgets - i think).
    I think it has power monitoring for the laptop in it. Also a whole lot of other goodness.

  • Why does the battery die before the power monitor puts the computer to sleep?

  • Faulty Power Monitoring Unit?

    I updated to 10.4.9 about a week and a half ago. I don't know if that has anything to do with my problem, but before that, I had no issues with my battery.
    Recently, I was using my Macbook, running on the battery, and with about 3:30 remaining, it shut off into sleep mode.
    I plugged it in and restarted it to find that my battery capacity went from 5200 mAh to about 550. That's TOTAL CAPACITY, not current charge.
    So, I called AppleCare, and they told me to reset my PSU and PRAM. Surely enough, I was getting a correct reading for my capacity and charge.
    I just charged my laptop before going to bed last night and I let my MacBook sleep while running on battery while I was at school. When I got home to use it, this is what the readings for my power were:
    Current Battery Capacity - 6533 mAh
    Original Battery Capacity - 5200 mAh
    Approx. Time Remaining - 47 hours 49 minutes.
    This was about 10 minutes after turning it back on, mind you.
    I tried to reset my PSU and PRAM...twice...but to no avail.
    Is my Power Monitoring Unit faulty, or am I not reseting it properly?
    Help is appreciated.
    NOTE: This Power monitoring problem only seems to occur when I let my MacBook sleep for long periods of time (about 10-12 hours). Could that have anything to do with it?
    MacBook (White) Mac OS X (10.4.9) 1GB RAM 80 GB HD SuperDrive 2.0GHz Core 2 Duo

    I am going into the Apple store tomorrow.
    I have done 7 PMU Resets and 5 PRAM resets, all to no avail.
    I swear, this battery is faulty. Please post new updates if you can. I may not be able to log on and reply because I'm having connection problems. Post any suggestions you can, other than a PMU or PRAM reset - those HAVE NOT AND WILL NOT WORK.

  • P67A-GD55 board stuck in "CPU is in 1 phase power mode" loop.

    New build: mobo: as stated, CPU: i5-2500k, Cooler: Cooler Master TX3, PSU: OCZ700SXSP, RAM: 4x2GB PNY DDR3-1600, GPU: EVGA GT440, HDD: WD500AAKX, DVD: LGGH22NS50.  System assembled without a hitch in Cooler Master Centurion 534+ ATX case.
    Moment of truth:  Switch PSU on. System launched into loop of CPU 1 phase power mode = on for fraction of second, off for 1-2 sec.  The indicator is led 1 of 6 lighting briefly with each cycle.  The FP power led lights up and the fans all spin during the brief on periods. Started disconnecting peripherals and power connections, removing ram and at each test there was no change.  Got down to just PSU and mobo with still no change.  Pulled CPU power connector leaving just mobo 24 pin and still no change.  Reseated CPU and switched coolers somewhere in the middle of that. 
    What have I missed that will get this system to boot?

    Last update to this thread, just to say problem completely solved with the replacement mobo from MSI.  This one booted up the way it should and my new system is purring and running quite cool under all default settings.  Have just two 120 mm case fans, one intake and one exhaust, plus TX3 cooler on the i2500k.  MSI software says CPU is running about 29 degees and NZXT sentry 2 fan controller says bottom of heatsink is 23-24, with all temps min the case < 25 and no warm air exhaust.  Must be the relatively mousy GPU (EVGA GT440) not cooking everything in the neighborhood.
    I didn't build this for gaming, just for running a very large number of browser, Excel, Windows Explorer et al windows at the same time without hanging.  It's doing that now under W7 Pro 64bit.   to MSI for backing up their warranty and   from me when I use the new rig.

    We have a solar power monitor that feeds information to the electricity company via our hub. It is connected directly to the router. Recently the connection has dropped. The cable is not loose. The electricity company suggest I contact BT to find out if a firmware update had been put through on my line, as that may have closed a port.
    I've spoken to three BT people on the phone, none of them knew what i was talking about. Can anyone here assist?
    Thanks

    If you had to manually forward any ports, then you would have to set them up again. This guide may help.

  • Power Monitoring with a Compact RIO

    Hello:
    Is there a means to monitor power using donuts and C Series Modules + LabVIEW?
    Thanks.

    Absolutely.  NI actually used to package up a cDAQ with a 3 phase current, and 3 phase voltage module and the free Electrcial Power Measurement.  I think NI realizes there is more money in selling stuff so they made the Electrcial Power Suite which is a non free software toolkit for LabVIEW which does do a bunch more stuff.  And they are suggesting you buy cRIO hardware which is much more expensive.
    But if all you want is 3 phase voltage, current, power, and stuff like power factor correction all you need is the following:
    cDAQ-9174 4 Slot Chassis
    cDAQ 9225 3 Phase Voltage Input 300VRMS
    cDAQ 9227 3 Phase Current 5ARMS
    Here are a few white papers.
    http://www.ni.com/white-paper/8198/en/
    http://www.ni.com/white-paper/8652/en/#toc1
    And the software mentioned

    http://sine.ni.com/nips/cds/view/p/lang/en/nid/209826
    What makes this work is that the voltage, and current modules are simultanious sampling.  This means each of the 3 phases can be measured at once.  Other DAQ hardware will have a slight time shift, and that affects the readings.
