IEEE519 ION template and PME report

[Liangchen1982]

Hi SE experts,

Is there a technical note about ION IEEE-519 template? I couldn't find one. Currently ION USA template has IEEE-519:2014. Any thoughts of when the latest version of IEEE519 firmware will be released? And perhaps IEEE-2800?

We’re using ION8650A for Power Quality monitoring and adherence to IEEE-519 (future IEEE-2800) requirements.  I am looking for some proper setup guidance of these functions in the meter, and the PME report. Except for the PME users manual, could you provide me any best practices or guidance document more specific to the IEEE519 feature? 

Thanks

Leo

Hello @Liangchen1982 ,

The Us template is supported by specific group within Schneider's US team. Have you reached out to the people who provided you with the template?

Most of the work comes from the modules inside the meter's template rather than firmware. Before you ask, no there is no document that provided details on the exact template design. The harmonics evaluation module does most of the heavy lifting inside the template. It is technically possible to configure these modules with limits as found in the 2022 version of IEEE519.

I do not have a meter with the template so I cannot say how easy or hard the configuration is to do.

The PME report is really quite simple. Inside the meter there are different counters for different phases and 95% 99% etc. These counts get logged under very specific measurement names. The report in PME will calculate (1-(count of intervals where limit is exceed)/(count of valid intervals)) if the calculate value is above threshold, report displays pass, otherwise report shows fail.

Regards,

Charles

Latest ION Setup also plays a part as each IEEE 519 Edition has different limits which must be programmed differently which is why there is a setup wizard allow user to select which edition they wish to employ.

If the template does not have 2022 support, then the wizard will only allow the user to select between Disabled and 2014.

Thanks Robert, long time no see, hope you are doing good:)

another question for you: How can I customize the setup assistant interface of IONsetup to allow me to input an external numerical value there? (I tried to create a topic and post this question but failed, not sure why, sorry.. )

Hello @Liangchen1982 ,

The wizard will look at the template string and determine if the template supports adding this feature or not. The ION8650 template that supports IEEE519 was created by the US organization and not the factory. Therefore, setup wizard can tell that template does not support everything that wizard would need to change to using the latest harmonic limits.  Note that you are working with an ION Meter, many many things are possible, including manually changing the limits.  

You can open the Harmonic Evaluation module and change the setup register to alter the limits to match the 2022 limits of IEEE519 standard.
