Figs. 3.61 and 3.62 show the RBFNN test output and error of phase A when an inter-turn fault occurs on phase A inside the stator of an induction motor. From Fig. 3.61 the RBFNN test output is equal to zero for first three samples and is equal to one for the faulty condition from 4 to 21 samples with good accuracy. This shows that the RBFNN is able to locate correctly the fault

occurring on phase A. The testing error is 5.2727 × 10-7 as shown in Fig.3.62.

From Fig. 3.63 it is clear that the RBFNN well learn the test data with good accuracy. Hence the RBFNN is able to

locate correctly the stator inter-turn short circuit fault occurring on A phase. The testing error is

very low i.e 4.0955 × 10-7 as shown in Fig.3.64.

error is 2.2727 × 10-7 as shown in Fig.3.66. Hence we conclude that the RBFNN is able to locate

correctly the fault occurring on phase A.
