1. 1 Three Phase Power Measurement Typically a waveform capture will be one or two cycles in duration and can be viewed as the actual waveform as a spectral view of the harmonic content or a tabular view Showing the magnitude and phase shift of each harmonic value Data collected with waveform capture is typically not saved to memory Waveform capture is a real time data collection event Waveform capture should not be confused with waveform recording that is used to record multiple cycles of all voltage and current waveforms in response to a transient condition 1 5 Power Quality Power quality can mean several different things The terms power quality and power quality problem have been applied to all types of conditions A simple defini tion of power quality problem is any voltage current or frequency deviation that results in mis operation or failure of customer equipment or systems The causes of power quality problems vary widely and may originate in the customer equipment in an adjacent customer facility or with the utility In his book Power Quality Primer Barry Kennedy provided information on different types of power quality problems Some of that information is summarized in Table 1 Electro Industries Gauge ech Doc E154713 The Leader In Power Monitoring and Smart Grid Solutions 1 17 1 Three Phase Power Measurement Cause Disturbance Type Source Impulse transient Transient voltage disturbance
