Connected a VFD to submersible today and before I even got it programed it had tripped on a ground fault. Bad spot in the drop cable. Does the drive actually charge motor and conductors before a start call?
ABB. Owner & well guy were a bit frustrated that I wanted the well pulled before we continued. We could have bypassed that feature but it failed our meg test with .3 meg @ 47volt. "Well it worked with the old starter" came up more than once. We were alll a lot happier when we found the dinged wire. 7.5 hp 480v 3ph.
Yeah, both times. :grin:Cool; it's always nice when the electrician turns out to know something nobody else would've suspected.
