Is it dangerous a low reading such as 1Kohm for IR I know you need to seriously investigate but if a 3 phase submersible pump is installed correctly wouldn’t the breakers/ fuses blow before the equipment is unsafe.
And is that L-L or L-E; and if the latter, just one L, two, or all three? I would suggest that you disconnect the motor and find out whether the fault lies in the motor or the fixed wiring (or both). It may seem like teaching Granny to suck eggs, but don't you need to establish where the fault lies before you can fix it? ?
