The results presented <strong>in</strong> the tables account for: real power P1h, reactive power<br />

Q1h and apparent power S1h, obta<strong>in</strong>ed for the basic harmonic of the measured<br />

current. The tables present only some selected but representative measurement<br />

results for various types of meters. Measurements were conducted for multiple<br />

meters of one type and only results from three meters of one type are shown <strong>in</strong> the<br />

tables so as to present the characteristic result repeatability.
