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.
That much leakage is very dangerous IF it passes through a human body.
For a pump that is presumably earthed, AND probably out of reach the risks seem small.
It is however a worrying sign WRT future reliability. If the pump is large and costly I suggest a full overhaul, if small and cheap, precautionary replacement might be prudent.
Apart from the potential dangers, energy is being paid for and wasted. About 50 to 60 watts is being wasted, depending on tarriff that could cost as much as a penny an hour. Or in the region of £80 a year.
Before condemming anthying, double check, preferably with a different instrument. Also double check that the observed result is not due to a pilot lamp, contactor coil, level switch or other ancillary item mis-connected between phase and earth, rather than between phase and neutral.
