I went on a service call to a dialysis clinic and found that they were damaging sensative electronic dialysis machines and also learned that they have to hand crank them. The clinic is located in an existing nursing home and the clinic part is fed from a new 75 kva transformer and all new wiring. However, the main that feeds the transformer is fed from the existing switchgear and there is an old hydro elevator motor that is still in use. Whenever the motor kicks on it sags all power in the building and causes all the lights to flicker as well as the new transformer. The dialysis machines as well lose power and are constantly going out. I have never seen surges like this before and was wondering if someone could help me figure out the best way to fix this problem and maybe what could have been done to prevent this before the new construction of the clinic took place.
I looked at the service itself and the feeds from Edison dont look big enough. ALso it is a 240 volt 3 phase with high leg and the transformer is stepped down to 208/120.
