Apparatus for harmonic analysis of waveforms in an AC electrical system |
摘要 |
A monitor for an ac electrical system generates on-line a display presenting the values, either in magnitude or as a percent of the fundamental, of 50 harmonics of any of the currents and voltages in the system. The display also incudes the phase angle of each harmonic relative to a reference waveform, which is preferably phase A-B voltage or phase A to neutral voltage./!
