About This Item
IEEE IEEE/IEC P62271-111/PC37.60/D7, Aug 2017 is an IEEE/IEC International Draft Standard focused on automatic circuit reclosers and fault interrupters for alternating current systems up to 38 kV. It addresses equipment used to interrupt and restore power after faults, which is important for distribution-system reliability and controlled fault clearing. For power, energy, and industrial applications, this draft helps frame technical expectations around design, ratings, and performance for medium-voltage switching devices.
About IEEE IEEE/IEC P62271-111/PC37.60/D7, Aug 2017
This draft standard sits in the technical area of medium-voltage switching and protective equipment, with emphasis on automatic circuit reclosers and fault interrupters. It is intended to support consistent requirements for devices that detect fault conditions, interrupt current, and then reclose when appropriate in AC systems up to 38 kV. As a draft, IEEE IEEE/IEC P62271-111/PC37.60/D7, Aug 2017 is most relevant where engineering teams need a common reference for product definition, testing alignment, and specification language.
Where is IEEE IEEE/IEC P62271-111/PC37.60/D7, Aug 2017 used?
This standard is commonly relevant in distribution networks, substations, and feeder protection schemes where automatic reclosers or fault interrupters are used to manage transient and permanent faults. It may also be applied in utility equipment procurement, product development, and test planning for switching devices serving lines, laterals, and other AC power circuits up to 38 kV. In industrial power systems, it can help define requirements for interrupting and restoring service in a controlled way.
Importance in practice
In practice, the standard helps improve consistency in how these devices are specified, evaluated, and compared. For manufacturers and purchasers, IEEE IEEE/IEC P62271-111/PC37.60/D7, Aug 2017 can support clearer compliance targets for ratings, insulation coordination, and operational behavior. For engineers, it reduces ambiguity when selecting equipment for fault interruption and automatic reclosing duties. That can lower integration risk, support safer system operation, and make testing and acceptance more straightforward.
