About This Item
IEEE P1246/D25, Oct 2020 is an IEEE Approved Draft Guide for Temporary Protective Grounding Systems Used in Substations. It addresses the engineering considerations for temporary grounding practices in high-voltage substation environments, where safe work conditions depend on reliable control of induced or fault-related voltages. As a draft technical document, IEEE P1246/D25, Oct 2020 is relevant to crews, engineers, and planners who need guidance for safer maintenance and switching activities.
About IEEE P1246/D25, Oct 2020
This draft guide focuses on temporary protective grounding systems used in substations, with attention to components, circuits, devices, and system-level application. It is intended to support consistent grounding approaches during energized-system maintenance or outage work, where grounding equipment must perform predictably under demanding electrical conditions. IEEE P1246/D25, Oct 2020 helps define a technical framework for selecting, applying, and reviewing temporary grounding practices so that field procedures align with recognized engineering guidance.
Where is IEEE P1246/D25, Oct 2020 used?
IEEE P1246/D25, Oct 2020 is typically used in substation work involving buses, switchgear, conductors, and associated temporary grounding leads or clamps. It is most relevant during maintenance, inspection, testing, and repair tasks where workers may need added protection from accidental energization, induced current, or backfeed conditions. The guide is useful for utility substations, industrial power facilities, and engineering teams responsible for planned outages and safe work execution around power, energy, and related electrical systems.
Importance in practice
In practice, this draft guide supports safer and more consistent grounding decisions by giving teams a common technical reference for temporary protective grounding systems. That can improve compliance, reduce ambiguity in work planning, and strengthen coordination between design, operations, and field crews. IEEE P1246/D25, Oct 2020 may also assist with procurement and testing by clarifying expected equipment characteristics and application practices. For substation environments, that consistency can reduce risk and help maintain reliable protection during maintenance work.
