Clip (a) Current transformers CT1, CT2, CT3, CT11, CT12, and CT13 (7, figure 11-2) should read 7.5 ohms at 77°F (25°C). (b) Current transformers CT4, CT5, CT6, and CT10 (8) should read 0.420 ohms at 77°F (25°C). (c) Current transformer CT7 (16) should read 0.089 ohms at 77°F (25°C). (d) Demagnetize the current transformers following the resistance tests by connecting secondary terminals to a variable AC power source such as a variac or similar device and slowly raise the current to 2 amps for CT1, CT2, CT3, CT11, CT12, and CT13 (10 amps for CT4, CT5, CT6, CT10, and CT7), then slowly lower current to 0 amps. (2) Current Test. WARNING SECONDARY TERMINALS SHOULD NOT BE LEFT OPEN WHEN AC CURRENT IS APPLIED. (a) Test CT1, CT2, CT3, CT11, CT12, CT13, CT4, CT5, CT6, CT10, and CT7, by wrapping 10 turns of a conductor around the current transformer. (b) Apply an AC current of 10 amperes to the conductor. (c) Current measured at current transformer terminals must be 86 milliamps for CT1, CT2, CT11, CT12, and CT13; 416 milliamps for CT4, CT5, CT6, and CT10; and 500 ma for CT7. (d) Replace defective current transformers. Replace rubber pads (21) when reassembling current transformer (16). c. Replacement. (1) Removal.  (See figure 11-2.) 11-5
