A voice-frequency transformer characterized by a closed core , a pair of identical balanced primary ( line ) windings, a pair of identical but not necessarily balanced secondary (drop) windings, and low transmission loss at voice frequencies. ( 188 ) Note: It permits transfer of voice currents from one winding to another by magnetic induction, matches line and drop impedances, and prevents direct conduction between the line and the drop.
