1564-2014 - IEEE Approved Draft Guide for Voltage Sag Indices
Description: This guide identifies appropriate voltage sag indices and characteristics of electrical[H2] power and supply systems as well as the methods for calculating them. Methods are provided for quantifying the severity of individual voltage sag events, for quantifying the performance at a specific location (single-site indices), and for quantifying the performance of the whole system (system indices). Multiple methods are presented for each. The methods are appropriate for use in transmission, distribution, and utilization electric power systems.
