Section 13.7: Generator Characteristics cont.

Example 13.6 cont.

I = 200A.

¬

KVL: Vf = Vt + Rser.I = 250V. + .04W´200A. = 258 V.

If = Vf/Rf = 258V./125W = 2.064 A. and by KCL:

Ia = I + If = 200 A. + 2.064 A. = 202.064 A.

KVL: E’ = Vf + RaIa = 258 V. + .06W´202.064A. = 270.12 V.

KVL: E = E’ + Vbrush = 270.12V. + 2V. = 272.12 V.

Note that Vbrush isn’t shown on the schematic
