NI Power Analyzer

Hello
I have to build power analyser(ExM 6000) using labview,I have gone through the power quality analyzer tool kit can i use it for the same?any heads up on how to start? I have NI PXI with analog input and analog output and digital I/O module. Any Example code?
Thank You

Hello,
It looks like Agilent/HP makes the 8990A, but I was not able to find a driver for it that we or Agilent has written for this device.
Since I am not familiar with the 8990A, I cannot recommend which drivers might be similar, but you are pointed in the right direction. Agilent themselves might know more about which models use similar command sets so that you can modify a driver easily.
Hope this helps.

Where can i find a Labview driver for the "8990a PEAK POWER ANALYZER" it's not on NI's site.

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.

LabVIEW Drivers for Norma 5155 power analyzer

I have several questions concerning a GPIB LabVIEW driver for the power analyzer NORMA 5155 (NORMA is now part of LEM company):
1- Has anybody programmed a driver specially for this device so far ?
2- Is it possible to use other similar drivers (LEM/NORMA 4000..6000) for it?
3- How would you approach building a suitable driver? (Instrument I-O Assistent ...,)?
Any answer could be helpful.
Andreas, Germany

1) There are no drivers for the 5155 at http://zone.ni.com/idnet97.nsf/browse/
(but perhaps someone beside NI has programmed a driver)
2) The same type of instrument from the same company will likely have a similar command set. The drivers for the 4000 and 6000 are Plug and play driver and not IVI drivers, so modifying them would be easy.
3) I would first call LEM tech support and ask what the difference between the commands sets of the the 5155 and 4000/6000 are. If LEM tech support is unable to give a good answer, then I'd try to get the manuals for the 5155, 4000, and 6000 to just compare the command sets myself. If they are very similar I'd just modify the old driver. If they are very different, I'd just make I/O assistant VI for each function in th
e manual, and I would have a low-level driver. Once you have this low level driver you can just combine functions to make higher level VIs.
Hope this helps!

Acquiring USB signal from power analyzer

I have a 6510e power analyzer that I would like to read in Labview. I have connected an RS232 cable from the back of it, through an RS232/USB adapter into a USB port in my laptop. I am having a hard time finding a way to read that USB data in Labview to manipulate it to get the power readings. Any help would be appreciated. Thank you.

You have not provided the vendor's name, the programming manual, or the code you have been trying.
Test the commands in the manual with a terminal emulation program such as Hyperterminal, TerraTerm, etc. and then try them with one of serial example programs that come with LabVIEW. Post back with specific problems and include any error codes you get.

Data Acquisition Solution for Measurement of Temp,V,I,P,Q,PF,f

Dear All,
I am facing one problem in selecting the Hardware,can anybody support me,
This is regarding DAQ Solution(cFP) for Measurement of Temperature,Voltage,Current,Active Power,Reactive Power,Power Factor and Frequency for a Motor.
Requirement is that, Measurement and Monitoring of Temperature,Voltage,Current,Active Power,Reactive Power,Power Factor and Frequency for a Motor
1)12 RTD Inputs(PT 100 Sensors)
2)3 Current(From 3 CT's) ,3 Voltage(From 3 PT's) [From these 6 Parameters,Active Power,Reactive Power,Power Factor,Frequency we have to derive ]
Hardware which i have selected is attached,please find the attachment..
RTD Module which i have selelcted is ok,but i have one doubt in AI Module Selection,
I selected AI 100 Module(8 Channel(Both V,I).12 bit,360 S/s[in this i have one doubt,i.e.360 Samples that to per channel or 360 Samples per 8 channels?) for taking 3 Voltage Signals from PT's and 3 Current Signals from CT's)
If we install and take signals from Motor,in reality harmonics(Max if we consider 8th Harmonic Components [8*50=400 Hz will be signal Freq]) will come into picture,
For finding frequency(From V,I wave shapes),atleast (5 Fs i.e.5*400=2kS/s i have to take right,correct me sir if i am wrong..)
Why we want this system is,currently,we are using Yokogava Power Analyzer for finding Voltage,Current,Active Power,Reactive Power,Power Factor and Frequency,But RTD it cant..,So we need total System with RTD SIgnals and above parameters to be monitored in a host PC without any Power Analyzer,i.e.our measurement system should be independent of Yokogava Power Analyzer.Again one problem is that Yokogava is giving Accuracy 0.02% in the measurement of Power and what about the accuracy of our system and for this,which Module shall i go for?)

Hi wayne.C,
Thank you very much for your reply,
Actually Interfacing the instrument for Power and remaining using Compact DAQ is also one more solution as u told,
but problem here is that,we are always dependent on the instruemnt.So i am looking for common Hardware platform
which will server both the purposes,and obviously,i will go for cRIO Solution,as sampling rate will be higher,
Thanks and regards,

I would like to know a question regarding interfacing with a Yokogowa WT130 utilizing a NI GPIB-USB-HS is possible in Dasy Lab

I have a Yokogowa WT130 power analyzer and I would like to use this to communicate to DASY Lab. The Yokogowa utilizes IEEE 488 communication and I was thinking of using the NI GPIB-USB-HS to connect the Yokogowa to the computer. I do know that DASY Lab is capable of utilizing IEEE 488 but I am confused on if I would neede a seperate driver for the Yokogowa or if the driver for the NI GPIB-USB-HS would allow communication. Any feedback would be greatly appreciated.

backhausr1,
I would recommend asking this in the DASYLab forum, which can be found here: http://forums.ni.com/t5/DASYLab/bd-p/50
You will likely get better and more prompt assistance.

I work in the power conversion industry and do these types of measurements all the time…
Do you want to just measure power quality or create and measure power quality problems?
What hardware are you using?
Power quality analyzer?
Programmable AC power source?
Fast Transient Generator?
Here is an example of what I do.
To create PQ problems I use a California Instruments AC source set to nominal power for the unit under test. Using Labview I program several transients consisting of fixed and random duration dropouts and surges. I also use a Schaffer Fast Transient Burst Generator to apply high frequency noise bursts directly onto power lines.
For measuring power quality I use a Voltech PM3000A power analyzer and Labview to measure everything from voltage, current, and frequency, to harmonics and %THD

NI -488.2 GPIB

I am Sze Yuen Cheng from Osram Sylvania Inc. I have a few questions about your NI-488.2 GPIB. I need to use the GPIB to interface a few Xitron power analyzer instruments with the computer by using Visual Basic 6, and this is the first time that I am using both Visual Basic and GPIB. I found 2 files from the NI-488.2 software CD: one is called Vbibi-32.bas and the other is Niglobal.bas. What are these files? Are they just the initialization and variable definitions for the GPIB hardware? Do I have to include these files with the Visual Basic program in order to communicate between the computer and the instruments through the GPIB? How can I include these files in the Visual Basic program? What are the most important things that I have to know
or acquire from the Vbibi-32.bas and the Niglobal.bas files in order to finish my task? I am going to attach these 2 files for your references.
If you need more information, please contact me at [email protected] or 847-726-6258.
Thank you,
Sincerely,
Sze Yuen Cheng

Hi,
You have found the right two files! These two files make up what we call the "language interface files" for VB. You can find out more here: http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3D90756A4E034080020E74861&p_node=DZ52353&p_source=external
In summary:
NIGLOBAL.BAS: global module containing predefined constant declarations
VBIB-32.BAS: source file containing NI-488.2 routine and NI-488 function prototypes
I always find that the best way to learn is by example. There should be some basic examples that installed with your NI-488.2 driver. If you installed it to the default path, it will be located in C:\Program Files\National Instruments\NI-488.2\Languages\Visual Basic
Take a look at those examples. They should hel
p you get on your way.

10g - merge 2 fact tables

hi, experts,
there are 2 tables
columns in A:
CK1
CK2
CK3
X varchar
Y varchar
Z varchar
FA1 double
FA2 double
FA3 double
columns in B:
CK1
CK2
CK3
FB1 double
FB2 double
FB3 double
CK1,CK2 and CK3 are the common keys of TABLE A and TABLE B.
if there is a table/pivot table having columns : CK1,CK2,CK3, X,Y,Z, FA1,FA2,FA3,FB1,FB2,FB3
I found that all FB1,FB2,FB3 are showing null.
how to solve?

i used to work on a very primitive tool called INFORMATICA POWER ANALYZER ( 10 YEARS BACK- 2001/2002 ) and OBIEE is a re incarnation of that tool. I think this feature is avaiable in OBIEE 11g ( pulling columns from different subject areas via implicit common DIMENSION tables )

Filter data in tdms file

I am needing to look at select data of a TDMS file in an analyze portion of a stat machine. The VI is to test both AC and DC motors. I am getting 18 different reading from a power analyzer. I am writting these to a TDMS file for ease of passing through the rest of the states. In the "Analyze" state I am wanting to look at 13 of readings an compare them to see is they are within tollerence. I will then use this check to highlight the reading green or red.
My questions are:
Should I even have an 'Analyze' state or should I do the analysis in the state that the reading is taken?
If I do use the 'Analyze' state is pulling the data from the TDMS file the best way to do this?
Also, if you see any other possible errors in the vi, please let me know. This is my first experience with LabView and it is steep learing curve.
Thanks,

Since you are using a State machine approach, I would suggest to keep that idea and add the Analyze state to keep the code organized. Plus, you can add a shift register to pass around the acquired data which will be more efficient than reading from the TDMS file.
For future reference, when using the state machine while you analyze, log, etc...you are forcing sequential execution and loosing time that can be used for hardware I/O. When this becomes a concern you can implement the following structure. Keep up the good work

Error VISA (Hex 0xBFFF001E) The specified state of the attribute is not valid, or is not supported as defined by the resource.

Hi,
First of all I need to say that I just beginning with the instrument control using Labview. For this reason, it's possible that the problem that i have would be easy to resolve. However, I have been looking for any solution for the forum, but unfortunately I can't fint anything.
Then the situation is the following: I'm trying to connect a power analyzer (Yokogawa WT1800) with the PC through GPIB. To achieve this objective I use the Agilent 82357B USB/GPIB Interface. The connection is done properly because I can see and comunicate with it through the NI MAX explorer.
In order to achieve the instrument control using Labview, I have downloaded and installed the Yokogawa WT1800 driver (ykt1800 Instrument Driver) using the NI Instrument Driver Finder tool. The problem that I have is that when I execute the provided examples I find the following error:
Error -1073807330 occurred at Property Node (arg1) in Yokogawa WT1800 Series.lvlib: Initialize.vi -> Yokogawa WT1800 Series Measure Continuos Normal.vi
Possible reason(s):
VISA: (Hex 0xBFFF001E) The specified state of the attribute is not valid, or is not supported as defined by the resource,
I tried to change the input arguments of the Visa open vi because I think that is there where is the problem but I can't achieve any solution. In the following image is attached the block diagram of the initialize.vi:
Any help is appreciated.
Thank you.
Solved!
Go to Solution.

Hi,
The Vi should work, I used it with a NI USB-GPIB interface. Can you use HighLight execution to see which property node is failing. Maybe your interface does not support the used property node.

Controlling a Load Drive using Modbus TCP or Ethernet IP

Hello,
My name is Francisco Loras. My team and I are looking forward to building a dynamometer in order to obtain test standards for motors. We're going to use a Load Drive in order to control the Load Motor. The Drives we have been looking at are either from ABB or from Yoskawa (a1000), both offer the option of connecting via Modbus TCP/IP or via Ethernet IP. I was wondering if someone has previously worked with them and could give me some feedback on either the drive or connection type. I would preferrably use Ethernet because the complete system we're building requires at least one more ethernet connection (for a Power Analyzer).
Besides this, we were counting on using a Chassis from NI to put everything together. When looking at the specific modules, we considered two options:
1- Using an ethernet module (from NI that fits in the Chassis) to drive in both the Power Analyzer and the Load Drive.
2- Using an ethernet switch setting specific IP addresses.
Has someone used any of these before? A switch would be close to 50 times cheaper than using the ethernet module itself so I'm a bit worried there might be something that limits it or that I'm missing (noise maybe?).
To conclude, I'm looking forward to se if someone has:
1) Used Ethernet IP or Modbus TCP/IP to control a Load Drive, which connection type is best if any.
2) Recommended any specific load drive
3) Experience with using an ethernet switch or an ethernet module.
Thankyou very much for your help and time,
Francisco
PD. If something is unclear (which I sense it is) please ask me and I can develop more on it.

Florasga,
Which ethernet module are you looking at? And what kind of chassis are you planning on using?
There's some more information on Modbus here. Also, have you seen this forum post?
