Hi,
All readings are from the same moment and the same instrument. The harmonics distortion is very low, according to the equipment. All the values are total, I'm not sure if the PF data in logging mode is displacement or real, but the harmonics are low.
If I could compensate the trafo...
Hi,
Thank you all for your answer. I still don't get the difference between PF value the Fluke 1735 is giving me (column one in my earlier post), and the value a calculate with the kW and kVar (column 4). Because I only get this difference when the kVar are negatives, I'm using the equation...
Hi,
I have a capacitors installed in the low voltage side of a 750 kVA transformer (12.5 kV/208-120 V). The utility meter is on the high voltage side of the transformer and the monthly average power factor on the bill is under the penalty limit of 0.9. Therefore I made some measurements with a...
"Reactive current 3 Amps.
Active current 4 Amps.
Total current 5 Amps.
If you correct the power factor to unity the total current will be reduced from 5 Amps to 4 Amps."
Hi waross,
But why in first place you have to use the 5 Amps. to calculate the losses (I^2R). I thought that only the...
Hi,
I have read that one of the benefits to increase the power factor through capacitor banks is the reduction of technical losses.
Here is my doubt, if I have a comercial kWh-kW meter in medium voltage and it's metering the active energy of a facility with a medium voltaje transformer (500...
