    Completely false like the man that wrote it.

    Sweden has a population of about 10 millions of persons, up to today Sweden made only 23659 tests per million of population that means 2.36% of population and Sweden is 56th in the world. About the absolute number of tests made by Sweden, currently the total number is 238800 and Sweden is 53th in the world.

    PF does not depend on the "active power negative value" but on the cosine of the phase angle between the real power and apparent power.

    LDM

    LOL, again an odd statement.

    The cosine of the phase angle between the Real power and Apparent power comes from the definition of PF equal to the ratio Preal/Papparent, as in a right triangle the cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse.


    Being measured S positive your statements "not depend" and "but" are again a fail.

    You can check making calculation based on PCE-830 displayed data of P (the real power) and S (the apparent power) computing -1.07/2.19 getting the PF=-0.488.

    Thus a negative value could in the example showed only have occured due to a miscalculation resulting from the wrong calculated Fourier components.

    LDM

    Wrong calculation of Fourier components due to what?

    Are you saying that PCE is not able to make the calculation? or was it defective?


    Write a math that demonstrates your statements otherwise yours are chat.

    I indeed intentional ignored those indicators but had seen them.

    But those likely where the result of the wrong frequency determination and as I stated as a consequence the measurement data was wrong. ( including the negative signs ).

    You are completely wrong, frequency and active power are two different circuits, parameters and measures.

    PF depends on active power negative value, not from frequency measure.

    LDM ,

    Part of the problem may be that there were 4 cables (3 phases plus neutral) attached to the ecat in December 2012, and which are connected in the strangest way.



    LOL,

    LDM ignored also negative active power indication PΣ and negative Power Factor PF, both impossible parameters. sign of an acquisition set-up completely unreliable.
