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, thebuilding 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.
