The revisions to the 1990 version of this standard include the following: Clarification of the difference
6、s between fused circuit breaker including intergrally fused and nonintegrally fused circuit breakers and separately fused circuit breakers as covered in IEEE Std C37.27 B7.a The revisions of IEEE Std C37.27 B7b were made concurrently with the revision of this standard. All units were updated to refe
7、rence metric units. Review was made concerning lightning impulse withstand voltage (BIL) requirements. No BIL requirements were added to the standard. Update of the requirements associated with demonstrating circuit breaker capabilities with consideration of operation at 50 Hz, 60 Hz, or for dual-ra
8、ted 50 Hz/60 Hz circuit breakers. Update of the requirements associated with the classification of insulating materials was made to the material definitions of UL 746A B9. The factors in Table 4 are based on the power frequency of 60 Hz. For 50 Hz circuits, the values in Table 4 can be used, but are
9、 conservative. There was discussion concerning the service condition for the minimum temperature. The issue is that there are two references provided: 1) reference to the temperature inside the enclosure housing of 5 C for the air surrounding the circuit breaker and 2) reference to the temperature o
10、f the air surrounding the enclosure as specified in IEEE Std C37.20.1 (which is 30 C).c In order not to hold up the publication of this standard, the original text in IEEE Std C37.13-1990 was used with one addition. Text was added to the application section that clarified that heaters should be used
11、 for low ambient temperature conditions. This issue will be reviewed in the next revision of this standard. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with the provisions of this standard does not imply compliance to a
12、ny applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements.
