What is the accuracy of PM8000 for demand readings?

[Sepehr_Zarrabi]

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!

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? 

Regards,

Charles

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.

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.
