2) Draw the equivalent circuit of Figure 3 based on the
equivalent circuit in Fig. 2 showing all the appropriate impedances
in per unit.
Note: Since the transformer model has two windings on the
secondary side, you can combine the impedances of the two windings
to make a single equivalent winding on the secondary side. In other
words, the secondary winding voltage is considered to be 240V and
the impedances R2 and X2 are the combined impedances of the two...
Magnetic Circuits y Part A - Calculate reluctances Learning Goal: To understand how magnetic structures can be analyzed by drawing an equivalent circuit, and to use the equivalent circuit to calculate magnetic fluxes and coll currents. When analyzing magnetic structures, the geometry is often complex enough that using the fundamental rules can be very difficult without numerical methods. However, there are approximate methods that are often sufficient for engineering calculations. When the magnetic field is mostly contained within cores of...
