impedance presented to the source by the magnetizing winding of a 2-tage inductive voltage divider when the measuring winding is energized by a voltage having the same amplitude an phase as the voltage at the magnetizing winding terminals, kaheastmelise induktiivpingejaguri magnetiseeriva mähise poolt allikale edastatav näivtakistus, kui mõõtemähist pingestatakse pingega, mille amplituud ja faas on samad kui magnetiseeriva mähise klemmide pingel
