Formula for reactive energy

MYTILOS PC 10 months ago in Tips and Tricks • updated by Support Manager 10 months ago • 1

Hi!

Can you please give me the formula I must add to arithmetic operation "f(x)" to calculate the total Reactive Energy (kWArh).

We have 3 phase system 230V phase - 400V pole.

Thanks

Hello,

See the demo for example.

https://dash.smart-maic.com/demo

There is a graph with reactive energy [kVARh]

But at large intervals the accuracy drops, since the Power Factor is the arithmetic mean.

Complete Reactive Energy Formula: VAR = VA * sinФ = W/cosФ * sinФ

(((d.W1/d.PF1)*Math.sin(Math.acos(d.PF1))||0) + ((d.W2/d.PF2)*Math.sin(Math.acos(d.PF2))||0) + ((d.W3/d.PF3)*Math.sin(Math.acos(d.PF3))||0) ) /1000
