An Alternative Strategy to Improve the Flicker Severity Measurement
Gutiérrez Ruiz, José Julio
; ; Saiz Agustín, Purificación ; ; ; (Elservier, 2014-07-12)
The IEC 61000-4-15 standard defines a flickermeter that is universally accepted as the meter used for the objective measurement of a disturbing light flicker. The accurate results provided by the IEC flickermeter under ... -
Effect of the sampling rate on the assessment of flicker severity due to phase jumps
Gutiérrez Ruiz, José Julio; ; Ruiz Ojeda, Jesús María ; ; Saiz Agustín, Purificación ; (IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ... -
Enhancing ventilation detection during cardiopulmonary resuscitation by filtering chest compression artifact from the capnography waveform
Gutiérrez Ruiz, José Julio; Leturiondo Sota, Mikel ; Ruiz de Gauna Gutiérrez, Sofía ; Ruiz Ojeda, Jesús María ; Leturiondo Arana, Luis Alberto; ; Zive, Dana; Russell, James Knox; Daya, Mohamud Ramzan (Public Library Science, 2018-08-02)
Background During cardiopulmonary resuscitation (CPR), there is a high incidence of capnograms distorted by chest compression artifact. This phenomenon adversely affects the reliability of automated ventilation detection ... -
Experimental Study of the Response of Efficient Lighting Technologies to Complex Voltage Fluctuations
; Gutiérrez Ruiz, José Julio; ; Saiz Agustín, Purificación ; ; (Elsevier, 2014-07-09)
The replacement of incandescent lamps with more energy-efficient lighting technologies has a direct influence on the way flicker is measured. The International Electrotechnical Commission (IEC) established in the 61000-4-15 ... -
Experimental Study of the Summation of Flicker Caused by Wind Turbines
; Gutiérrez Ruiz, José Julio; ; Saiz Agustín, Purificación ; ; Ruiz de Gauna Gutiérrez, Sofía (MDPI, 2019-06-22)
Integration of wind energy into the grid faces a great challenge regarding power quality. The International Electrotechnical Commission (IEC) 61400-21 standard defines the electrical characteristics that need to be assessed ... -
Flicker Characteristics of Efficient Lighting Assessed by the IEC Flickermeter
; Gutiérrez Ruiz, José Julio; Saiz Agustín, Purificación ; ; ; (Elsevier, 2013-10-13)
We present an experimental study of the behavior of modern lighting technologies under supply voltage fluctuations. Some studies have reported that flicker severity measurements could exceed the compatibility levels ... -
Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
Lodetti, Stefano; ; Gutiérrez Ruiz, José Julio; Leturiondo Arana, Luis Alberto; ; Saiz Agustín, Purificación ; Melero, Julio J.; Bruna, Jorge (MDPI, 2019-03-01)
The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lampsmainly LEDhave been subjected to real RVCs and their response ... -
Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
Ruiz Ojeda, Jesús María; ; Gutiérrez Ruiz, José Julio ; ; ; Saiz Agustín, Purificación ; (IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
