What is the accuracy of PM8000 for demand readings?

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!

Re: What is the accuracy of PM8000 for demand readings?

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.
