    That's usually from switching to battery power and back, a client of mine once had a bad power cable leading to his office, dropping voltage from 230V to 190-200V under load, this was right on the switch point for the UPS, so it kept switching back and forth between power sources. So grab your multimeter and measure line voltage.
