Trying to understand a power study done a few years back on one of our lines. It says there were volatge sags on one phase (277) that went as low as 244 and lasted a range of 1/4 cycle to 1 millisecond?
If I understand correctly on 60Hz power that 60 times a second and one cycle is 1/60th of a second which would be 16.6 milliseconds per cycle correct? Which would make a quarter cycle 4.15ms?
So it lasted 1ms to 4.15ms?
