What is the accuracy of PM8000 for demand readings?

Sepehr_Zarrabi · ‎2020-12-17

Looking for the accuracy of the following demand measurements in the PM8000:

- Current demand

- Active power demand

- Reactive power demand

- Apparent power demand

Thank you!

The biggest issue with demand accuracy spec is that a test can span a huge dynamic range (signal variation during the interval). For steady state lab conditions and proper configuration, the demand accuracy should be the same as power accuracy.

Hello @Sepehr_Zarrabi ,

I think I need a bit more of the context behind this question. Is there a standard you are trying to meet I do not know about?

Hello Charles,

I don't think this is a spec-related question. My BDS reached out to me with this question. I believe the question came from a customer. We can get in touch with her if you need more info. Please reach out to me directly.
