Demand real power and energy

[Janevski]

Hello everyone, 

I need to ask some questions regarding the connection between real/reactive energy and 

the demand real/reactive power.

For example, I know that the PM3255 meters can calculate "Active power sliding window demand delivered-received".

If you multiply this demand with the time interval for which the demand was calculated, you get active (real) energy signed

(delivered - received). 

On the other hand, the PM5300 meters (particularly PM5331) calculate a parameter simply called "Demand Real Power". 

I also know that the meter can show 4 types of real energy: delivered, received, signed (delivered - received), absolute 

(delivered + received)

My question is this: If you multiply this "Demand Real Power" with the time interval for which the demand was calculated, 

what kind of real energy would I get for PM5300? (Delivered, delivered-received, delivered+received)

Thank you for your help.

Hello @Janevski,

I have moved your post to the metering forum. 

@Ramasamy_N Would you be able to answer the question?

Hello @Janevski 

The PM5300 & PM3255 power demand values are calculated based on the Delivered Energy (into the load) power values and not supported the demand calculation for Received Energy (out of load).
