I have a Fluke logging meter set-up in a 4000 amp 277/480v service. One event showed A phase voltage dip to 180.9 volts for 0.327 seconds. Is this dip long enough and low enough to create problems for PC's, UPS, and other electronics? A phase is consistenly running between 267-271 volts, B & C phase 273-276. Amp loads are balanced +- 10%.
