A digital multimeter is set up as shown in the illustration to evaluate the single-circuit stator windings of a squirrel cage induction three-phase motor. The following readings are taken: From T1 to T2 reads "OL" ohms. From T2 to T3 reads "OL" ohms. From T3 to T1 as shown reads "1.6" ohms. What condition is indicated? Illustration EL-0219 |
A) Phase A (associated with T1) and Phase C (associated with T3) are short-circuited. Phase B (associated with T2) is undamaged. |
B) Phase A (associated with T1) and Phase C (associated with T3) are undamaged. Phase B (associated with T2) is open-circuited. |
C) Phase A (associated with T1) and Phase C (associated with T3) are open-circuited. Phase B (associated with T2) is undamaged. |
D) Phase A (associated with T1) and Phase C (associated with T3) are undamaged. Phase B (associated with T2) is short-circuited. |
