IEEE C37.015-2009

IEEE C37.015-2009 is a technical guide for the application of shunt reactor switching in power and energy systems. It addresses the practical behavior of reactor switching equipment, helping engineers consider operating conditions, electrical performance, and system effects when applying this type of switching. For utility and industrial power applications, the standard supports more consistent design decisions and can help reduce switching-related risk in reactive power compensation schemes.

Overview of IEEE C37.015-2009

This standard focuses on the application of shunt reactor switching, a specialized topic in high-voltage power systems where reactors are used to manage reactive power and voltage conditions. IEEE C37.015-2009 provides guidance that is useful when evaluating how switching devices and system characteristics interact during reactor energization and interruption. It is intended to support sound engineering practice by clarifying the technical considerations that matter for reliable operation, coordination, and equipment selection in power networks.

Typical use cases

IEEE C37.015-2009 is commonly relevant when specifying or reviewing shunt reactor switching duties for transmission substations, grid compensation equipment, and other power system installations that use reactors to control voltage. It may also be useful during procurement, system studies, and equipment coordination for switching devices intended to operate with inductive loads. Engineers can use it as a reference when planning operating procedures, assessing switching performance, or comparing candidate equipment for a given network application.

Why it matters

Proper application of shunt reactor switching affects system reliability, switching performance, and the long-term condition of connected equipment. IEEE C37.015-2009 helps bring more consistency to technical evaluation, which is important when managing transient behavior, limiting operational uncertainty, and supporting safer procurement decisions. For organizations working with power system switching equipment, the standard can help reduce design and application errors while improving alignment between project requirements and expected field performance.
