About This Item
C37.013-1997 is a technical standard for voltage generator circuit breakers rated on a symmetrical current basis, providing guidance for power equipment used in energy and industrial applications. It helps define how these breakers are rated and evaluated so their interrupting and operating capabilities can be compared consistently. For engineers, specifiers, and procurement teams, C37.013-1997 supports clearer selection and more reliable application of circuit breakers in electrical systems where symmetrical current ratings are important.
About C37.013-1997
This standard addresses the rating basis for voltage generator circuit breakers, with emphasis on symmetrical current considerations. In practice, that means it is concerned with how breaker performance is described and assessed for generator-related switching duties and associated fault conditions. As a superseded technical document, C37.013-1997 remains relevant for understanding historical rating practices, legacy equipment specifications, and archived compliance references in power system engineering.
Where is C37.013-1997 used?
C37.013-1997 is typically used in generator switchgear applications, utility power installations, and industrial electrical systems where circuit breakers must be selected for generator-connected duty. It is especially relevant when reviewing equipment ratings, comparing breaker capabilities, or documenting technical requirements for generator circuits. The standard may also be consulted during maintenance, replacement planning, and engineering review of older installations that were designed around symmetrical current-based breaker ratings.
Importance in practice
In practice, this standard helps reduce ambiguity in breaker ratings and supports more consistent design and procurement decisions. By clarifying the rating basis for voltage generator circuit breakers, it can aid compliance checks, improve equipment matching, and lower the risk of misapplication in critical electrical systems. For organizations managing legacy assets, C37.013-1997 can also provide a useful reference for testing records, documentation review, and performance comparison.
