Regarding the update interval of the PM8000 harmonic amplitudes

[T.Okada]

Hello,

I have a question about the update interval of the PM8000 harmonic amplitudes.
Is it 1 cycle or 1 second or 3 seconds?

Thanks,

Okada

Hi @T.Okada 

To comply with power quality standards like IEC 61000-4-30 Class S, depending on selected 'Aggregation Method', the PM8000 processes harmonics using specific time windows that are updated every 3 seconds (which is default and represents a 150-cycle window at 50 Hz or a 180-cycle window at 60 Hz) or every 10 minutes.

You will find more information in ION Reference -> Harmonics Measurement Module

Hi @Mehran_Mehrnia,

Thank you for your prompt reply.

I understand the measurement cycle of the harmonics

and I checked it with the actual device, and it was just as you say.
