About This Item
IEEE PC37.113/D3.5, Sept 2024 is an IEEE draft guide for protective relay applications to transmission lines, written for power, energy, and industry applications. It focuses on how relays are applied to protect transmission circuits, helping engineers evaluate protection concepts, coordinate settings, and support reliable fault detection. For teams working with line protection schemes, this technical document provides a practical reference for design and application decisions where system continuity and safety are important.
Overview of IEEE PC37.113/D3.5, Sept 2024
This draft guide addresses protective relay applications for transmission lines, a core topic in high-voltage power-system protection. IEEE PC37.113/D3.5, Sept 2024 is intended to help clarify application practices for relaying functions used on transmission assets, where fault clearing, selectivity, and dependable operation are critical. The standard is relevant to engineers who specify, review, or maintain protection schemes and who need a consistent technical basis for applying relays within power transmission environments.
Typical use cases
IEEE PC37.113/D3.5, Sept 2024 is typically used when selecting or reviewing protective relays for overhead or cable transmission lines, including projects involving substations, utility transmission corridors, and industrial power networks with high-voltage line protection needs. It may support relay setting studies, protection coordination, engineering specifications, and commissioning checks. The guide is also useful when comparing application approaches for line fault protection, distance relaying, pilot schemes, and other transmission protection workflows.
Why it matters
Transmission line protection has a direct effect on service reliability, equipment stress, and personnel safety, so clear application guidance matters. IEEE PC37.113/D3.5, Sept 2024 can help reduce ambiguity when designing or evaluating relay schemes, improving consistency across engineering, procurement, and testing activities. It may also support better compliance with internal utility practices and more defensible protection decisions, especially where fast fault clearing and dependable operation are essential to minimize outages and system risk.
