For the purposes of this document, the Ibllowing terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause,4
characteristic oltage (of a voltage sagj: A single-event characteristic that combines the voltages in the three phases providing one single value corresponding to the sliding-window root-mean-square Crms) voltage as defined for single-phase recordings. The characteristic voltage is the lowest of the three per-unit phase-to-phase rms voltages, and the three per-Unit phase-to-ground rms voltages after removing the zero- sequence component.
declared soltage: The nominal voltage or a value of a voltage different from the nominal voltage obtained by agreement between the electricity supplier and a consumer.
NOTE—See IEC 6lfl00-4-30.
depth (of a voltage sag): The difference between the reference voltage (either or V5) and the residual voltage. It is generally expressed in percentage of the reference voltage.
NOTE—See I EC 61000-4-30.
duration lola sultagr sag: The length of the interval between the time when the root-mean-square Irms) voltage drops below the sag threshold and the time it subsequently rises ahose the sag threshold.IEEE 1564 pdf download.
