Abstract :
The project for developing recommended practice for the establishment of voltage sag indices was approved by the IEEE in January 2000. Since then, the task force P 1564 met twice a year and developed a draft document. This paper presents the current state of discussions and a summary of the latest draft D2. Next to retained voltage and duration, as defined in IEC 61000-4-30, this paper discusses three-phase characteristics, voltage-sag energy indices, SARFI-indices, and voltage-sag tables. Triggering level and time aggregation are also briefly discussed.
