About This Item
IEEE PC57.13.3/D2.1, May 2024 is a draft technical document focused on grounding practices for instrument transformer secondary circuits and cases. In power, energy, and industrial applications, these grounding requirements help support safe operation, stable measurements, and consistent installation practices. By addressing how secondary circuits and enclosures are grounded, the standard helps reduce risk from fault conditions, stray voltages, and unintended current paths in transformer-based metering and protection systems.
IEEE PC57.13.3/D2.1, May 2024 overview
This draft guide provides technical direction for grounding instrument transformer secondary circuits and cases in electrical power applications. It is relevant where current transformers and voltage transformers are used for metering, control, or protection, and where secondary-side grounding affects accuracy, safety, and system behavior. IEEE PC57.13.3/D2.1, May 2024 is aimed at improving consistency in design and installation decisions by outlining how grounding practices should be approached in these specialized circuits.
Typical use cases
This standard is typically used when specifying or reviewing grounding arrangements for instrument transformers in substations, switchgear, control panels, and industrial power distribution systems. It may apply during engineering of protection and metering schemes, inspection of transformer secondary wiring, or selection of installation practices for secondary cases and enclosures. IEEE PC57.13.3/D2.1, May 2024 is especially useful where reliable secondary grounding is needed to support commissioning, maintenance, and safe operation.
Why this standard matters
Proper grounding of instrument transformer secondary circuits can help reduce hazards, improve measurement integrity, and support dependable protection performance. For utilities, industrial facilities, and equipment suppliers, the guidance in IEEE PC57.13.3/D2.1, May 2024 can assist with compliance review, design control, and procurement decisions. It also provides a common technical reference for testing and installation work, which may help limit misapplication, inconsistent grounding practices, and avoidable reliability issues.
