About This Item
IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 is an IEC/IEEE draft international standard focused on high-voltage switchgear and controlgear, with particular attention to 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, helping define a common basis for design, performance, and testing. For utilities and engineers, it supports more consistent specifications and safer equipment selection.
What is IEEE P62271-111/IEEE PC37.60_D5, Feb 2018?
This draft standard addresses the technical requirements and application context for automatic circuit reclosers in medium-voltage AC systems. IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 is part of the broader high-voltage switchgear and controlgear family and is aimed at equipment that must detect faults, open the circuit, and then automatically reclose after a set interval. That makes it relevant to design, rating, insulation, operating duty, and verification practices for recloser equipment.
Where is IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 used?
This specification is commonly used in utility distribution networks and other power systems where automatic fault clearing and service restoration are important. IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 is relevant to overhead and substation-adjacent installations, feeder protection schemes, and equipment planning for alternating current systems up to 38 kV. It may also support procurement and engineering work for switchgear applications where reclosers are needed to improve continuity and reduce outage duration.
Why is IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 important?
Using IEEE P62271-111/IEEE PC37.60_D5, Feb 2018 helps align equipment expectations across design, testing, and procurement. For automatic circuit reclosers, clear requirements matter because operating performance, interruption capability, and reclose behavior directly affect system reliability and safety. The standard can reduce ambiguity when comparing products, support more consistent compliance checks, and help engineers specify equipment suitable for medium-voltage service conditions. It is especially useful where predictable fault response is essential.
