ng at a few random files, it looks like the range for both legs is about 10 volts. Ive checked frequency a few times in the past with the fluke scopemeter, both at home and work (i live 7 miles away from work) and have noticed it to jump between 58 and 62 hertz. Which makes sense because our older alarm clock needs to be corrected every month of so. I've been meaning to start logging frequency-- not got around to it yet. Steve

instead of the utility > published ones. Some empirical evidence from a third party would help a lot. 70 and 142 seem more than a bit unreasonable. How long did they stay at that level? I like Jim's suggestion of asking the guys who are collecting the data. ---------- I've been using my UPS to monitor line voltage. It's got commands to read the min/max input voltage since the last time you asked. My software writes a line to the log file every 5 minutes or more often if the line voltage changes by more than 2 V. It runs about 30K per day. Mostly, things are boring: 120-125 V. Occasionally I see a glitch. I should write some code to scan the old files and collect statistics. -- These are my opinions, not necessarily my employer's. I hate spam.
