What is Harmonics?
Harmonics is a , integral multiples of the fundamental frequency, introduce distortion in non-sinusoidal voltage or current waves, quantified as Total Harmonic Distortion (THD) expressed as a percentage of the pure sine waveform.
What is harmonic indices?
In the power quality industry, specific index values, such as Total Demand Distortion and Total Harmonic Distortion, are instrumental in assessing service quality by gauging distortion caused by harmonics, serving as valuable metrics for evaluating system performance.
What is voltage and current distortion?
Voltage distortion refers to any deviation from the nominal sine waveform of AC line voltage, while current distortion is any deviation from the nominal sine waveform of AC line current.
What is PQM?
In high-reliability facilities, Power Quality Monitoring, integral to design, assesses the supply system's performance and power conditioning equipment, identifying potential interaction issues with facility loads.
What are the purposes of power quality monitoring system?
> Implementing preventive maintenance
> Performing load analysis
> Conducting equipment diagnostics
> Carrying out long-time surveys
