Excerpt from Influence of Wave Form on the Rate of Integrating Induction Meters Fig. 8 shows the effect of changing the harmonic from 10 per cent to 25 per cent and 50 per cent, keeping the phase constant. Meters 1 and 2 show the least change in rate; meter 4 runs faster, and meters 3 and 5 run slower and show the greatest change in rate. Fig. 9 shows for three meters the same thing as fig. 8, except that the phase of the har monic is 900 different. Meters 1 and 2 show relatively small changes, but both run faster on the flat than on the sine. Meter 3 runs nearly 3 per cent slower on the 50 per cent harmonic than on the sine.
