ما هو ال vector group for transformers وماذا نعنى بمحول Dyn11 او Yd11 او Dyn5 مع رسم الفيكتورجروب

What is a vector group? And what is the meaning of Dyn11? And what is the meaning of Yd11? The Vector Group It is a term given to the directional group of electric power transformers, and their compatibility is a condition of connecting transformers in parallel And the Vector Group method for connecting High and low voltage of the transformer as well as the phase shift angle phase displacement Between low voltage windings, high voltage windings, or otherwise, the lag angle coils or lead offers low voltage coils over high voltage coils How to read the directional group of power transformers? D Hv side delta, Y Side star Hv, d lv Side delta y lv the side of the star 0-12 the phase displacement in terms of clock position is a multiple of 30 degrees The phase offset of the LV winding in reference to the HV winding (lag or lead Practical example of what we mean by Dyn11 Religion 11 D delta high voltage side is connected The high-pressure side connects delta-triangular files A low voltage side star is connected Hand low pressure link files astral star n is neutral The neutral, neutral, or cold line 11 stage offset 11 o'clock 11 'Oclock Phase shift angle: the secondary curtain winding voltage advances the primary delta by 30 ° How do we calculate the phase displacement? The product of the last number 11 x [30] = 330 To learn how to draw to download photos, pictures, photos, discoveries, details and annotations
