IEEE 1668-2017 IEEE Recommended Practice for Voltage Sag and Short Interruption Ride-Through Testing for End-Use Electrical Equipment Rated Less than 1000 V

IEEE 1668-2017 IEEE Рекомендуемой практики для напряжения Провисания и перебой Ride-Through тестирования для конечного использования Электрического оборудования Номинальных Менее 1000

This document is a non-industry-specific recommended practice for voltage-sag ride-through performance and compliance testing for all electrical and electronic equipment connected to low-voltage power systems(with nominal/rated voltage less than 1000 V) that can experience malfunction or shutdown as a result of reductions in supply voltage lasting less than one minute. The recommended practice includes definingminimum voltage-sag immunity requirements based on actual voltage-sag data. A clause dedicated to the detailed analysis of voltage sags experienced by end users provides insight into real-world voltage sags.Testing procedures and requirements for test equipment are clearly defined within this document to reflect the electrical environment, including single-phase, two-phase, and three-phase, balanced and unbalanced voltagesags. The recommended practice also defines requirements for certification and test reporting, includingcharacterization of voltage-sag ride-through equipment.
