TR1 1 TRANSFORMERS（TR1 1变压器）.pdf

TR1- 1 TRANSFORMERS EQUIVALENT CIRCUIT OF TWO-WINDING TRANSFORMER Dots • show the points of higher potential. There are applied following conventions of arrow directions: -for primary circuit -the passive sign convention (receiver, the power is absorbed), -for secondary circuit - the active sign convention (source, the power is released). Full representation of the real transformer Features: Real transformer with two windings (primary secondary) of different numbers of turns (usually). Sinusoidal voltage supply. The windings are characterised by their resis
