Recent field tests on motors in service on pipelines and powerhouse systems have shown that the switching surge voltage appearing at the motor terminals during initial energization for starting frequently reach magnitudes approaching 2.0 per unit normal crest line-to-ground operating voltage with time-to-crest as short as 0.2 As. This is more severe than normally believed and may endanger turn-to-turn insulation.
