IEEE P1246/D15, Apr 2019

IEEE P1246/D15, Apr 2019 is a draft guide for temporary protective grounding systems used in substations, with practical focus on components, circuits, devices, and system-level application. It addresses how temporary grounding arrangements are typically planned and applied to help reduce electrical hazard during maintenance or switching work. For engineers and buyers working with substation equipment, this technical document supports more consistent grounding practices, safer work planning, and clearer expectations for protective system design.

IEEE P1246/D15, Apr 2019 overview

IEEE P1246/D15, Apr 2019 provides guidance for temporary protective grounding in substation environments where energized equipment may need to be isolated, worked on, or verified safe for access. As a draft guide, it is relevant to engineering teams evaluating grounding methods, conductive connections, and related hardware used to establish protective bonds. The document is useful where consistent temporary grounding practice is needed to support safe operation, maintenance coordination, and technical review of grounding-related requirements.

Typical use cases

This standard is typically consulted when planning temporary grounds for substations, including work on buswork, switchgear, transformers, and other power apparatus that may require protective bonding during outage work. It may also guide selection or review of grounding cables, clamps, connectors, and related devices used in field procedures. In power, energy, and industry applications, IEEE P1246/D15, Apr 2019 can help align work practices with substation safety and engineering expectations.

Why this standard matters

Temporary protective grounding is a critical part of substation work control, and IEEE P1246/D15, Apr 2019 helps define a clearer technical basis for that task. Using a common guide can improve consistency in design decisions, procurement of grounding hardware, and verification of field procedures. It also supports safety reviews by reducing ambiguity around how temporary grounding systems should be applied, helping lower operational risk and improve coordination between engineering and maintenance teams.
