wrong value power factor !!

[oussama415]

I use the counter with the ES32 , I have a problem with the power factor sometimes for loads I have the right value, sometimes for other loads I have a lower value !!! for example i should have 0.98 but the function eic.GetPowerFactorA() return 0.52 how do i solve this problem?

What kind of load are you using to test this? Also, what else are you using to measure the power factor?

I put an asynchronous motor 1.1KW it gave me good results also for a 120W led lamp and when I put a set of 2 to 3 LEDs, at the current level it's ok but for the power factor no. I compared my measurements with a certified smart meter

Are you able to verify the real power and apparent power (VA) of the LED lamp? The power factor can also be decreased if the current transformer is backwards.

I tested the current sensor in both directions, always the same result !!! Here the example :

-------------------Phase 1 : ------------------------ Voltage 1 : 218.97V Current 1 : 0.50A Active Power 1 : 0.109 KW Reactive Power 1 : 0.018 KVAR Apparent Power 1 : 0.110KVA Power Factor 1 : 0.9870 Déphasage 1 : 0.16 Temp : 28.00°C Frequency : 50.00Hz -------------------Phase 2 : ------------------------ Voltage 2 : 226.38V Current 2 : 0.33A Active Power 2 : 0.039 KW Reactive Power 2 : 0.065 KVAR Apparent Power 2 : 0.075 KVA Power Factor 2 : 0.5130 Déphasage 2 : 1.03 Temp : 25.00°C Frequency : 49.95Hz -------------------Phase 3 : ------------------------ Voltage 3 : 218.85V Current 3 : 0.00A Active Power 3 : 0.000 KW Reactive Power 3 : 0.000 KVAR Apparent Power 3 : 0.000 KVA Power Factor 3 : 0.0560 Déphasage 3 : 1.51 Temp : 28.00°C Frequency : 50.00Hz

in phase 2 instead of having 0.98 I had 0.50!

Were you able to figure anything out with this? I assume you're reading the current for the corresponding voltage phases? If not that will also throw off the Power factor reading.

Hi John,

That's too advanced for me. I am using the same code on github: https://github.com/CircuitSetup/Expandable-6-Channel-ESP32-Energy-Meter/blob/master/Software/ESPHome/6chan_energy_meter-add-on_jp8-jp11.yaml

It worked for me, and I am getting correct values for 3 installations (3 mainboards, and 5 addons). The only problem am having is with CT8. So I don't think it is a Power factor issue.

This was a different setup than yours with a 3 phase system.
