Definition: | the current flowing through a line terminal of a winding when a given voltage is applied at rated frequency, the other winding(s) being open-circuited
NOTE 1 – Normally the applied voltage is the rated voltage and the energized winding, if fitted with tappings, is connected on its principal tapping.
NOTE 2 – The no-load current of a winding is often expressed as a percentage of the rated current of the same winding.
