I have a 30hp phase perfect that goes into a sub panel that feeds a haas vf2ssyt at 240v and it also feeds a 240-480v transformer that runs my haas st-10 lathe . when I have power going to the transformer the led lights in my vf2 will flicker a bit . if I turn on the st-10 the light will flicker in there too . not sure what is causing this . I checked the voltage between phases and all is good and I do not see any real fluctuation between phases . everything works fine on the lathe but the flickering light gets a bit annoying . here is a picture of the plate on the transformer .
