I'm trying to figure out how to measure energy consumption with a power meter.
It reports for the three phases:
- Total Active Energy
- Forward Active Energy
- Reverse Active Energy
- Total Reactive Energy
- Forward Reactive Energy
- Reverse Reactive Energy
Where: Total Energy = Forward - Reverse, for both Active and Reactive versions.
The question is what is Forward Reactive Power and Backward Reactive Power?
My understanding is that reactive power is casued by inductive elements in the machines, causing a "backward" flow (from machine to generator). What is then the Reverse Reactive power?
If I'm interested to find out my energy bill cost then (if I understand correctly):
- for residential consumers: I should look at total active energy
- for industrial consumers: it varies, but sometimes also the reactive part is billed. Would this be the total reactive?
Thank you! I'm not an engineer, apologies if the question is nonsensical.
