I started a small shop in a 900 sf building I have on my property in
the country. Before I moved in the prior owner had a woodshop, the
building has its own power and gas. 11 months ago I bought a
Bridgeport Milling machine with a phase converter. The power off the
transformer is shared with 2 other neighbors. Everytime I turn on my
mill there is sudden dimming of the lights and it did it with the
neighbors lights in there house too. I called my power company and
they came out and changed the transformer from 5 kva to 25 kva. I
still see little bit of a power drop in the neighbors lights, I work at
night and now that it is getting darker out I can see the issue. Now
that I am getting busier now and getting a lathe in 2 weeks I am
wondering if I can get my power on my own transformer, do you think it
will be expensive or should pay an electrician to upgrade my power to
200 amp service which would make the power company come out and put in
even a bigger transformer? I have a 100 amp service and all I have is
a mill and then I am getting a lathe that runs on 220 single phase.
