reactive power meter
(OP)
Hello , I have a little problem , because I tried to find an device that can be used as power factor regulator, such as estamat or varlogic or dmk , and can measure on-line the total amount of compensated reactive energy.
Thank you.
Thank you.

Thank you for your replay.

Use this figure (KVAHRs) with the readings from the revenue meter to determine the power factor both with and without the correction capacitors. (Add the KVARHR reading from the meter on the capacitor bank to the KVAHR reading on the revenue meter to determine what the power factor would be without the correction capacitors corrected.)
Check the Power factor penalty on the power bill.
Refer to the power company's tariffs to determine what the power factor penalty would be without the correction capacitors connected.
The saving in power factor penalties is the figure normally used to evaluate power factor correction savings.
Every installation has I^R losses in the conductors. These losses are usually a very small percentage of the total energy cost. Power factor correction may give a small reduction in already small I^R losses.
The energy saved by power factor correction is only significant in very long, heavily loaded feeders and long transmission lines.
The normal benefit of power factor correction is in reduced penalties on the power bill, not energy savings.
