Answer / engr. l. o. osuji

Hi,
Voltage by definition is the potential difference between
two points e.g phase-neutral is 230V and line-line is 440V
according to you. You cannot measure the voltage of a line
alone. If, however, you insist on measuring the voltage of
the line alone your result will be zero. It must be between
the line and something else.

Answer / aboli

I jst wnt to add something in previous answer.In AC System
all three phases are 120 degrees apart & if u take vector
sum of it u will get 0.Hence it follows KVL.
Vector Vr+Vector Vy+Vector Vb=0.

How do I know if a transformer is saturated? I am doing the simulation of the saturation of a transformer, but what parameter tells me when a transformer is saturated? How do you calculate? is on the plate?, there is a rule that can help me? How could model? I understand the saturation occurs when the flow can no longer bind to the other winding, this is given to certain current, this current is the same that appears as the highest in the bale of features? Thank you for your help Eduardo Alvarez Guatemala
