Power Conditioning for Small Machine

01/30/2019 11:10 AM

Hey guys

I have a small machine onsite that continues to have electrical failure.

We believe this is caused by the sites bad harmonics in their power system.

We cant do anything about thier stuff so i need to find a way to keep our machine from blowing up. Small single phase 20A 110V machine.

Anyone know of a small power conditioner or something similar to try?

"A small machine with electrical failure" is pretty vague...

If you think its your power distribution, then call someone to check your system harmonics and pF. Then after you get the results, do something about it!

Also, get the local utility supplier to check the neutral connections all the way back to the star point of the local distribution transformer. It wouldn’t be the first time a user has had a problem with over voltage caused by a loose neutral connection somewhere. ��

What leads you to believe that the failures are the result of "bad harmonics" at the site? What kind of "failures" are you experiencing on what kind of components?

As a general rule, ferroresonant power conditioners are fairly impervious to allowing line side harmonics to get through and affect down stream components. But ferroresonant power conditioners have other problems to contend with, based on the type of load side devices you want to power. So without more details, there is no good answer.
