Engines do not start - what could be the reason?
Hello. What is the reason? All three phases are present, the starter is turned on, there is power to the motors (4 pcs.), But not one starts! They don’t even buzz. I haven’t seen this before.
Hello! The trivial question is - where are the 3 phases? At the beginning of the line or at the end? In the terminal block of engines what? Did the windings ring? Are they serviceable not torn off? Is the star assembled? What voltage? (Although then they would buzz). There can be no more reasons in principle.
