Conclusions
-
1.
There exists in electrostatic voltmeters a rigid relationship between the instrument's frequency error and the effect of higher harmonics in the measured voltage source.
-
2.
The effect of higher harmonics can easily be calculated by means of the error due to frequency variations, and this computation can serve to evaluate the above effect.
-
3.
The total effect of the 2nd, 3rd and 5th harmonics never exceeds the standard tolerances in electrostatic voltmeters whose error due to the change of frequency up to the top limit of its nominal frequency range does not exceed 1/5 of the permissible basic error.
