Voltage interruption

Data records

  • In IEEE 1159-2019 a voltage interruption is the disappearance of the supply voltage on one or more phases, qualified by a duration term, momentary, temporary or sustained; clause 4.4.2.1 measures an interruption by its duration because its magnitude is always below a small fraction of nominal.

  • IEEE 1159-2019 defines momentary and temporary interruptions as short-duration rms variations with complete loss of voltage on one or more phase conductors, distinguished only by the duration band each occupies within the short-duration category, and notes that the reclosing practice of the protective device sets the duration of a fault-caused interruption.
