2. Welders, boilers, elevators and cranes, which rapidly change loads, can also be sources of flickering lights if they are connected to the electrical system. Flicker can also cause unwanted switching of UPS units to battery mode as well as problems with sensitive electronic equipment that requires consistent voltage (e.g., medical laboratories). Flicker meters POWER QUALITY MEASUREMENT EQUIPMENT They include everything from very fast transient over voltages (microsecond time frame) to long-duration outages (hours or days time frame). Power quality problems also include steady-state phenomena, such as harmonic distortion, and intermittent phenomena, such as voltage flicker. Fluorescent lamps can occasionally develop a fault that can cause them to have noticeable flicker. These machines include large motors when they are starting up, machinery with cyclo-converters such as rolling mill drives and mine winders, as well as machines that use static frequency converters such as ac motors and electric arc furnaces. Flickering lights can have an adverse effect on health, causing fatigue, lack of concentration, migraines and in some cases, epileptic shock. 3. One of the many aspects of power quality that can affect electricity users is voltage fluctuation that causes lights to flicker. The meter measures voltage transient events at up to 50 MHz speeds. Voltage fluctuation. Whenever the electrical load changes, the supply voltage is affected proportionately. A power quality analyzer or energy logger can measure voltage fluctuation, help you avoid nuisance tripping and find what equipment is causing flicker issues by using the event capture feature, which provides waveforms and additional data. Some people can see a higher rate of flickering light than others. Flicker Produced by Harmonics Modulation Description: Oscillation of voltage value, amplitude modulated by a signal with frequency of 0 to 30 Hz. While health effects are a main concern, the production line of an industrial plant can also be affected. The UIE/IEC Flickermeter is the standard for flicker measurement. Flicker is the name given to changing light intensity caused by fluctuations in the voltage. 16 Cutler-Hammer IQ Analyzer Cutler-Hammer … 15 Portable Monitors Hobo Pro Series Hobo Shuttle. A potential source of flickering lights is machinery with rapid fluctuations in load current or voltage. After a while, diagnosing power-quality problems and identifying how to solve them becomes an art as well as a science. The severity of reaction and sensitivity varies from person to person. After a while, diagnosing power-quality problems and identifying how to solve them becomes an art as well as a science. Visit our contact us page for repairs, technical support and other questions. Indeed, flickering lights are a common symptom of a power quality issue. Implementation of flicker meter in power quality analyzers ... requirements for IEC flickermeter implementation and a more general but also rather superior requirements for a class A power quality analyzer sampling methods. Most people have seen this occur in their house; when the refrigerator or the furnace starts, some of the lights may dim. Fluke 1742, 1746 and 1748 Three-Phase Power Quality Loggers, Fluke 345 Power Quality Clamp Meter - Electronic Power Meter. Fluorescent lamps can occasionally develop a fault that can cause them to have noticeable flicker. Workers can feel tired and unable to focus as flicker can impede personnel productivity and your bottom line. Power quality is a worldwide issue, and keeping related standards current is a never-ending task.
