IEEE C37.013-1993

IEEE C37.013-1993 is a technical standard for AC high voltage generator circuit breakers rated on a symmetrical current basis. It addresses the design and rating considerations that apply when these breakers are used in power, energy, and industrial applications, where dependable interruption of high-voltage generator circuits is critical. By defining a consistent framework for ratings and related performance expectations, the standard helps support equipment selection, engineering review, and more reliable system planning.

Overview of IEEE C37.013-1993

This standard provides guidance for AC high voltage generator circuit breakers intended for symmetrical current rating practices. In practical terms, it helps engineers and purchasers understand how the breaker should be specified for generator-side service, where switching duties can be demanding and coordination with the electrical system is important. IEEE C37.013-1993 is relevant when evaluating breaker capabilities, comparing equipment offerings, and aligning technical requirements with the expected operating conditions of power generation and industrial installations.

Typical use cases

IEEE C37.013-1993 is commonly used when specifying or reviewing generator circuit breakers for high-voltage AC systems in plants that generate or manage electrical power. It may be applied during equipment procurement, design checks, and technical evaluation of breaker ratings for generator connections, station service arrangements, or related power system interfaces. The standard is especially useful where symmetrical current basis requirements need to be clearly understood for generator protection and switching applications.

Why it matters

Using IEEE C37.013-1993 helps bring consistency to the way AC high voltage generator circuit breakers are rated and assessed. That consistency matters for safety, coordination, and procurement decisions, because unclear ratings can lead to mismatched equipment or weak engineering assumptions. For compliance and testing workflows, the standard provides a common reference point that supports more dependable comparisons between products and helps reduce risk in critical power and industrial installations.
