Hi,
Very new to this forum so excuse any faux pas's.
Was wondering if anyone has come across this situation: Was doing some insulation testing as part of our planned maintenance and came across a motor that gave an odd result.
Capstan Motor 440V/60Hz, 24kW, Star/Delta configuration.
Removed all wiring and tested between windings 1U,1V,1W and earth and all 3 showed approx 1550 MOhm so pretty normal but between the phases all showed 0 Ohm. Almost like they were all shorted together.
Motor seems to be working normally.
Any explanations?
