Duration
[edit]For the uninformed, the article does not give an appreciation that the duration of a fault event is in the scale of milliseconds. Perhaps some further explanation regarding to that aspect. --Davagh (talk) 17:22, 17 December 2014 (UTC)
Under Voltage vs. Low Voltage
[edit]Low voltage is defined by Electropedia as follows
low voltage (abbreviation: LV)
a set of voltage levels used for the distribution of electricity and whose upper limit is generally accepted to be 1 000 V a.c.
Therefore, 'low voltage' is not the precise term, as FRT capability means e.g. to run through a voltage dip of ~150 ms length, but not down below 1000 V a.c. but rather something like 30% of nominal voltage: If the nominal voltage is 10 kV, that means you need an immunity for voltage dips down to 3000 V which is not low voltage. 'Under voltage' is the correct term, as it describes a threshold (eg. pu = 0,3).
