IEEE 1453-2004

The scope of this project is to develop a recommended practice for measuring voltage fluctuations on AC power systems including a measurement protocol. Recommend limits for the voltage fluctuations using the recommended protocol. The purpose of this recommended practice is to provide basic information for the design of an analog or digital flicker measuring apparatus. This recommended practice also sets tolerable limit values for flicker severity. Specifically, this recommended practice adopts the IEC 61000-4-15 for a functional design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to be constructed. A method is given for the evaluation of flicker severity on the basis of the output of flicker meters complying with this recommended practice. This recommended practice will supersede 3.9.2 and Figure 3-8 in IEEE Std 141-1993 [B5] 1 and 10.5.1 and Figure 10.3 in IEEE Std 519-1992 [B6]. New IEEE Standard - Inactive-Withdrawn. Adoption of IEC 61000-4-15. Voltage fluctuations on electric power systems sometimes give rise to noticeable illumination changes from lighting equipment. This phenomenon is often referred to as flicker, lamp flicker, and sometimes voltage flicker. This recommended practice provides specifications for measurement of this phenomenon and recommends acceptable levels for 120 V, 60 Hz and 230 V, 50 Hz AC electric power systems. It does not make any flicker emission specifications for certification of individual products manufactured for use on these systems.
