Szukana fraza: [Abstrakt = "In the article has been presented the results of research the external luminaries with use Fluke 434\/PWR Power Quality Analyzer. The measurements of voltage value and current value, their waveforms, active, reactive and apparent power, power factor and THD ratio for voltage and current was performed. The authors focused mainly on checking the contents of higher harmonics in current and voltage. The tests were performed to determine the impact of modern outdoor lighting fixtures equipped in LEDs on the electrical lighting installation. The study was based on Evolume 1 luminaire, produced by Fagerhult, fitted in four power LED. The total active power of luminaire is equal 22 W."]
