About This Item
IEEE P1246/D9, Apr 2011 is a draft guide focused on temporary protective grounding systems used in substations. It addresses the practical safety considerations involved in grounding portable and temporary equipment during maintenance, switching, and outage work. For power and energy applications, this type of technical document helps support safer work practices, more consistent engineering decisions, and better control of electrical hazards in substation environments.
Overview of IEEE P1246/D9, Apr 2011
This draft guide is intended to help define how temporary protective grounding systems are selected, applied, and used in substations. IEEE P1246/D9, Apr 2011 sits within the technical context of power system equipment and electrical safety, where grounding practices can affect worker protection and system reliability. Its guidance is especially relevant when crews need to establish a controlled grounding arrangement before working on energized or potentially energized substation components.
Typical use cases
IEEE P1246/D9, Apr 2011 is typically consulted during substation maintenance planning, switching work, outage preparation, and field procedures that require temporary grounding leads or assemblies. It may be used by engineers, utility personnel, and contractors responsible for grounding buses, conductors, switches, and other substation equipment before hands-on work begins. The draft guide is also useful when reviewing work methods, specifying grounding hardware, or aligning internal procedures with a consistent technical basis.
Why it matters
Temporary grounding is a critical safeguard in substation work, and IEEE P1246/D9, Apr 2011 helps support that safeguard with clearer technical direction. Using a defined guide can improve safety planning, reduce variability in field practices, and support better control over installation and removal of grounding systems. It may also help organizations document expectations for procurement, inspection, and use, which can be important for compliance-oriented maintenance programs and risk reduction.
