3.1
Voltage dip
The root mean square value of the power frequency voltage at a certain point in the power system suddenly decreases to 0.1pu~0.9pu, and after a short duration of 10ms~1min
Return to normal.
[GB/T 30137-2013, definition 3.1]
3.2
Short interruption
The root-mean-square value of the power frequency voltage at a certain point in the power system suddenly drops below 0.1pu, and resumes after a short duration of 10ms~1min
normal phenomenon.
[GB/T 30137-2013, definition 3.2]
3.3
Voltage sag tolerance
The ability of electrical equipment to maintain normal operation even when a voltage sag occurs in its power supply.
Note. Rewrite GB/T 32507-2016, definition 2.8.22.
