Harmonics: Test View
Harmonics generates test signals consisting of a fundamental voltage or current signal and superimposed harmonics. Depending on the used CMC test set, signals with a frequency of up to 3 kHz (i.e. 60th harmonic at 50 Hz or 50th harmonic at 60 Hz) may be generated.
Harmonics allows defining the fundamental of three voltage and three current signals, and – superimposed on those – any combination of even and odd harmonics. The harmonics thereby can be entered either in percentages or absolute values. Harmonic signals can be output directly or exported as COMTRADE files. A timer starts at the moment of harmonic injection and stops on a trigger event. The response time is indicated.
Harmonics features both a static output mode and a sequence mode. In sequence mode a sequence consisting of three states can be injected:
- Pre-signal: fundamental wave
- Signal: fundamental wave and harmonics
- Post-signal: fundamental wave
