Harmonics and Flicker Testing

About Harmonics Testing

Harmonics testing is a critical aspect of assessing electrical power quality. It involves the examination of electrical waveforms to identify and quantify the presence of harmonics. Harmonics are unwanted frequency components that exist as integer multiples of the fundamental frequency, which is typically 50 or 60 Hz in AC power systems. These harmonics can be generated by non-linear loads such as computers, electronic equipment, and power electronics. The purpose of harmonics testing is to measure the magnitude and phase angle of each harmonic component, assessing their impact on the power system. This testing is essential because excessive harmonics can lead to voltage distortion, increased losses, and the overheating of equipment, potentially causing operational disruptions and damage. By conducting harmonics testing and comparing the results to established standards like IEEE 519, organizations can ensure compliance and take corrective actions if necessary, such as installing filters or modifying load configurations.

Flicker Testing Services in Canada

Flicker testing focuses on evaluating the quality of electrical power by measuring and analyzing rapid and repetitive variations in voltage or light intensity known as flicker. Flicker can be observed as annoying and visually perceptible variations in lighting, particularly when large, fluctuating loads are present in the power system. Flicker testing employs specialized equipment called flickermeters or flicker analyzers to record voltage variations over time and calculate flicker severity indices, such as Pst (short-term flicker severity) and Plt (long-term flicker severity). These indices quantify the severity and perceptibility of flicker, helping to assess its impact on sensitive equipment and lighting systems. Flicker testing is crucial because excessive flicker can lead to reduced visual comfort, annoyance, and even potential health concerns in extreme cases. Compliance with standards like IEC 61000-4-15 is essential to ensure the quality of electrical power and mitigate the effects of flicker through appropriate corrective measures if needed.
