a. What does it physically mean if an Ohmmeter measures 'infinite' Ohms between the primary and secondary of a transformer, but a megger reports zero Ohms? b. Does a transformer have inrush current when it is first powered? c. Describe what FCBN means on a transformer nameplate, and the conditions when this rating is important.
