Only if it includes batteries. Many of the lower cost ones are more just surge suppressors than anything.

Tripp Lite offers a number that will work for you.

Expect to spend $100 or so to get one that will fit your needs.

For that low a voltage dip and 11 machines, nope. Pointless to have a battery back up as it would trip the second it switched. They aren't designed for that kinda draw. I own a furman power conditioner in my studio. There are surge strips that will auto shut off/trip on brown outs for 1/5th the price.

Your power company is likely violating federal regulations if your voltage is falling below 108 volts. I would call the power company and if they are not responsive I would tell them I am going to call the Department of Energy and any other applicable agencies.

Have you looked into solar? Don't have it myself, but if it will bump up your voltage, it will do it at exactly the right time.

Before you call the DOE, double check with a different meter. Just to be sure.

Call the power company. They have to maintain a certain voltage level. They will send out an engineer to check your transformer, service wire and replace it if it is undersized.

Yes, and the power company should be willing to check the voltage at the meter. If it is low at the meter then it is their problem to adjust/fix, and if it is only low in your house (house side of the meter) then it is likely a problem in your panel or wiring.
Also, the guy that comes out will likely be a lineman rather than an Engineer. Engineers are not hands on with Utility power.

You are taking a risk by playing even 1 game when the voltage drops that low. You are putting excess strain on voltage regulators.

Several folks with low line voltage have reported success preventing resets by installing my daughterboards...

another possibility, you might have a main breaker warming up on ya, acting somewhat as a resistor. a slightly loose clip on the meter itself? a main incoming wire barely too small to carry the load warming up. power company guy oughtta be able to find the issue pretty quick.

Yup, leave this one to the power company. You shouldn't have to pay a cent or waste your own time wondering if the problem is external. Good luck! Hopefully they figure it out.

I was going to say you better check the power at the box first before calling the electric co. You may have issues they cite you on right away. Above that though, I had issues with mine at one point be just a couple votes below. Once I noted I was having issues with a type of device sensitive, they came out and cranked out the power at the nearest whatever (you can tell I don’t know what they did ) and I was a couple volts above after that and good ever since.

Thanks what I was thinking also.

Best to check as close to the panel FIRST before you bring in witnesses.

You may just have a in wall connection about ready to let go due to high impedance from a loose screw.

Great advice here. Check with the power company. General rule at least in the Phila and surrounding areas 5% residential voltage range although that's based on a hour; shorter durations they allow as much as 50%... It gets tricky but you're pretty low. Definitely start with the power company and make sure they're supplying what you're paying for.

If you like to read, there's lots of good stuff on the subject. IEEE Standard 519

Table didn't copy through correctly but you should be less than 5% drop.
Table 1.
IEEE Std 519-1992 Harmonic Voltage Limits
Voltage Distortion Limits
Bus Voltage at PCC
Individual Voltage
Distortion (%)
Total Voltage
Distortion THD (%)
69 kV and below 3.0 5.0
69.001 kV through 161 kV 1.5 2.5
161.001 kV and above 1.0 1.5
NOTE: High-voltage systems can have up to 2.0% THD where the cause is an HVDC terminal that will
attenuate by the time it is tapped for a user.

Your problem could be after the meter and therefore your financial responsibility. The only way to test before the meter is having the power company come out and do it. That would be a good place to start.
I just finally got the power company out to my house last week after determining the issue was before the meter.

I have 125V on one leg and 101V on the other incoming wires (before the meter) with a heavy load applied. They could not find the exact cause but counted 27 homes on the one transformer with mine being at the end of the line

Their is something called a variac that you can get. I have a triplite 4 winding one. Some more expensive ones have variable windings so the output voltage is always 120v +/- .1 volt. These are not cheap though and probably would run > $1000. They are sometimes used for high end audio/video where the SMPS's will not tolerate such a voltage swing like with your pins.

You mean they couldn't care less......!!!..........Joey

Not sure on Ca power regulations but in NJ my brother had a leg out on his panel,instead of calling me he called the power company to come out and diagnose his problem,well they charged him $110 as they considered it a Nuisance call as it had nothing to do with their equipment.
Turns out the aluminum wire feed to the Main breaker box on one leg corroded and due to the high resistance burnt a hole in the main breaker as no anti-corrode paste was applied Lucky his house didnt catch fire.
Call your power supplier and see what and if they charge a fee.

Being it was winter time i went to NJ and swapped out his main[was cheaper $$] in about 5 hours. I even called the Power co. to tell them i was pulling the meter because i was not waiting for them nor get charged for it.
The tag on the meter has still not been replaced yet [8 years ago]i even told them to put a new one on because i was cutting it to remove the meter. So much for communication.

I'm actually really surprised they play at all with 103, especially WPC's!

The power company most certainly will send out an engineer for this not a lineman. Lineman construct the jobs designed by the engineers.

I am a former medium voltage EE and there is no way we were doing any hands on work. The Linemen/technicians are the only people that are typically certified to install and test the equipment.
If a BSEE is doing testing on power lines then that electrical engineer is underemployed.

We have PE engineers processing voltage complaints. I don't disagree they're under employed.

Excellent news. Glad you got it all worked out.
