why voltage swells and dips???

Answer Posted / jamsheer

Actually voltage dip is the sudden decrease of rms voltage of transmission line.And voltage swell is the temporary increase in RMS value of AC voltage with the magnitude of the retained voltage between 110% and 180% of the rated voltage.These are mainly due to the fault occurring on any of the power system components.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
