Published by testguy, November 23, 2019. Website: testguy.net Flicker, Transients and Noise Repetitive voltage reductions in lighting circuits can be detected by the human eye, a phenomena known as “flicker.” The term flicker refers to a very specific problem related to human perception of light produced by incandescent light bulbs, not necessarily general voltage fluctuations. Some commonContinue reading “PQ Analysis: Flicker, Transients and Noise”

PQ Analysis: Undervoltage, Overvoltage, Sags, Swells
Published by testguy, November 23, 2019. Website: testguy.net Undervoltage, Overvoltage, Sags, Swells The second most simple type occurs when voltage at the load drops below a minimum rated voltage or climbs above a maximum rated voltage for some period of time. Depending on how long these conditions last, they may be referred to as undervoltage or overvoltageContinue reading “PQ Analysis: Undervoltage, Overvoltage, Sags, Swells”
PQ Analysis: Power Interruptions
Published by testguy, November 23, 2019. Website: testguy.net, Power Interruptions The most simple type of power quality problem occurs when power delivered to an electrical load goes away, this is called a “power interruption.” The different types of power interruptions are classified according to their duration. A momentary interruption is a complete loss of voltage on one or moreContinue reading “PQ Analysis: Power Interruptions”
Understanding Current and Voltage Harmonics
Published by L&T Electrical & Automation, Website: lntebg.in Source: https://www.lntebg.in/about-us/blog/understanding-current-voltage-harmonics/ Current and voltage harmonics are often used interchangeably. At most places, only harmonics is quoted and whether the values pertain to current or voltage is not mentioned. The differentiation can be done on the basis of their origin. Understanding Total Harmonic Distortion The current andContinue reading “Understanding Current and Voltage Harmonics”
