100MOhm or more under normal ambient
temperature and humidity when the
megger reading between the windings
and the frame is DC500V.
Under normal ambient temperature and
humidity, sufficent to withstand 1kV at
50Hz applied between the windings and
the frame for one minute following a
period of continuous operation.
