Is possible to have neutral current harmonics evaluation in ION8650A?

Hi all!

Is possible to have neutral current harmonics evaluation in ION8650A?

If so, please give me a advice.

Thanks in advance!

I found this topic that helps with calculating the module of neutral current:

https://community.se.com/t5/Power-Metering/True-RMS-current-for-neutral/m-p/23269#M68

But I can't put that calculated value into the FFT module for I4. So I could have the harmonic evaluation from it. The I4 used is always zero and I can't change the input of the FFT.

The process described in the KB is on a per-harmonic basis. There is no I4 input to the meter to feed into FFT. 

The ION8650 meter already comes with the modules already in the template.

Hi Charles!

Thanks for the input.

So that calculation should be done for each individual harmonic, is what you mean?

And about the modules that you said ION8650 already have, you  mean the individual per phase harmonics,  coming from the HME (Harmonics Measurement) ? Because for neutral individual current I didn't find any  module...

[Charles_Murison · Accepted solution]

Correct, calculation would have to be done for each individual harmonic. The meter already has per phase harmonic informaion, no additional modules required. The harmonic modules get information from modules that get information form modules etc that read signals directly connected to the meter so there is nothing for netural current directly.
