Conclusions
-
1.
The rectifying instrument's error due to the wave form of current or voltage depends on the frequency and amplitude of the effective harmonics and is a periodic function of the phase difference between the higher and the 1st harmonic.
-
2.
The maximum rectifying instrument's waveform error with a 10% content of higher harmonics with respect to the fundamental* does not exceed 5% irrespective of the instruments's class of accuracy.
-
3.
A rise in the content of effective harmonics displaces the error curve towards negative values.
-
4.
The maximum error is produced by a curve containing the 1st and 3rd harmonics, and its maximum possible value occurs for a phase difference of 180° and a ratio of A3/A1 ≈ 0.6 between them.
-
5.
A rectifying instrument's error with a voltage (current) curve containing several harmonics (up to 6) does not exceed the maximum error due to the 3rd harmonic for the same nonlinear distortion coefficient.
