This document is a non-industry-specifi
The purpose of this recommended practice is to clearly define test methods and ride-through performance for determining the sensitivity of electrical and electronic equipment to voltage sags. Analysis of real-world sags provides the foundation for both test methods and performance criteria, aligning themselves as closely as possible to the end user's electrical environment. The recommended practice will define the characteristics in terms of the depths/magnitudes, durations, phase angles, and vectors of voltage sags required to relate to real-world voltage sags. The recommended practice will show how different voltagesag testing methods can be used to simulate real-world sags. End users will be able to use the recommended practice in their purchase specifications to ensure the required level of equipment performance. In addition, end users can use the voltage-sag criteria as a performance benchmark for existing equipment. This recommended practice can be used to provide a benchmark that can be used to identify equipment that has enhanced ride-through characteristics.
