About This Item
19-1938 is a superseded technical document on AIEE Oil Circuit Breakers, covering the design and application context of oil-filled switching equipment used in power systems. As a standard in the power, energy and industry applications field, it helps define expectations for breaker construction, interruption performance, and related engineering practice. For equipment selection, legacy system support, or historical reference, 19-1938 remains useful when working with older oil circuit breaker specifications.
About 19-1938
This standard focuses on AIEE oil circuit breakers, a class of high-voltage protective equipment that uses oil as part of the interrupting and insulating medium. 19-1938 is relevant to the technical requirements and operating characteristics associated with that equipment type, especially where consistent breaker performance and safe interruption behavior are important. Because it is superseded, it is mainly used as a reference for legacy installations, archived engineering data, and comparison with later protection standards.
Where is 19-1938 used?
19-1938 is most relevant in power distribution and transmission environments that still contain oil circuit breakers, including substations, utility switchgear, and industrial electrical networks. It may also be consulted during maintenance planning, replacement work, or documentation review for older breaker assemblies. In practice, it supports teams that need to understand historical AIEE requirements, assess compatibility of legacy equipment, or interpret older design records tied to oil-insulated switching and fault-clearing apparatus.
Importance in practice
Even though superseded, 19-1938 can still matter for safety, compliance review, and engineering consistency in legacy power equipment. It gives a point of reference for procurement decisions, inspection criteria, and performance expectations where oil circuit breakers remain in service. Using the standard helps reduce ambiguity when comparing older installations, documenting equipment condition, or planning upgrades. For organizations managing inherited infrastructure, it can support more controlled maintenance and lower operational risk.
