Essential measurements: Electricity waveforms with numerical values like resistance, diode, continuity and capacitance measurementsHarmonics are periodic distortions of voltage, current, or power sine waves. Harmonics in electric power distribution units will often be caused by non-linear hundreds for example switched manner dc electric power mater

Harmonics are periodic distortions of voltage, existing, or electricity sine waves. Harmonics in electric power distribution systems tend to be brought on by non-linear hundreds like switched mode dc energy provides and adjustable speed motor drives.Bị nhiễu loạn bởi nhiều yếu tố bên trong và bên ngoài, chỉ số chứng khoán T
