IEEE PC37.60/P62271-111_D9, Sept 2018

IEEE PC37.60/P62271-111_D9, Sept 2018 is an IEC/IEEE approved draft international standard focused on high-voltage switchgear and controlgear, specifically automatic circuit reclosers for alternating current systems up to and including 38 kV. It provides technical direction for equipment used to interrupt and restore power after temporary faults, supporting safer and more consistent design and evaluation. For manufacturers, utilities, and engineering teams, this standard helps frame requirements around performance, application, and compliance.

Overview of IEEE PC37.60/P62271-111_D9, Sept 2018

This draft document addresses the technical context of automatic circuit reclosers within medium-voltage and high-voltage power systems. IEEE PC37.60/P62271-111_D9, Sept 2018 is relevant where switching devices must operate repeatedly and reliably under fault conditions while remaining suitable for alternating current systems up to 38 kV. It is closely tied to high-voltage switchgear and controlgear practice, giving users a reference point for product specification, engineering review, and conformity assessment in power and industry applications.

Typical use cases

This standard is commonly referenced for distribution automation equipment, feeder protection schemes, and recloser selection in utility networks. It is useful when specifying devices for overhead lines, substations, and other installations where temporary faults may be cleared and service restored automatically. IEEE PC37.60/P62271-111_D9, Sept 2018 also supports product comparison, procurement reviews, and technical coordination for systems that require controlled switching behavior within AC networks up to 38 kV.

Why it matters

In practice, the standard helps reduce uncertainty in how automatic circuit reclosers are designed, tested, and applied. Using IEEE PC37.60/P62271-111_D9, Sept 2018 can improve consistency across procurement and engineering workflows, especially where compliance with high-voltage switchgear expectations is important. It also supports risk reduction by encouraging clearer alignment between equipment ratings, operating behavior, and system requirements, which matters for reliability, safety, and maintenance planning.
