IEEE 367-1987

IEEE 367-1987 is a technical standard for evaluating electric power station ground potential rise and induced voltage resulting from a power fault. It is relevant to grounding analysis in power, energy, and related communication environments where fault conditions can create hazardous touch or transfer voltages. By defining a recommended practice for this calculation, IEEE 367-1987 helps engineers assess risk, support safer station design, and improve coordination between power systems and nearby equipment.

IEEE 367-1987 overview

This standard focuses on the methods used to determine ground potential rise at an electric power station and the induced voltages that may appear during fault events. It is especially useful when grounding performance must be reviewed alongside station layout, fault current levels, and nearby conductive paths. IEEE 367-1987 provides a practical reference for engineering studies that support design decisions, system reviews, and technical documentation tied to station grounding and fault response.

Typical use cases

IEEE 367-1987 is commonly applied in grounding studies for substations, generating stations, and other power facilities where fault currents can affect personnel safety and connected systems. It may also be used when evaluating induced voltage on communication circuits, control wiring, or metallic paths near a faulted station. Engineers and consultants often rely on the standard during new design work, retrofit assessments, and coordination studies for equipment and interfaces exposed to electrical disturbances.

Why this standard matters

Ground potential rise and induced voltage are practical safety and reliability concerns, especially in facilities with dense electrical and communication connections. IEEE 367-1987 helps provide a consistent engineering basis for analysis, which can support safer grounding design, clearer procurement requirements, and more defensible study results. Using a recognized method can also reduce uncertainty when comparing alternatives, documenting compliance efforts, or reviewing the impact of fault conditions on station equipment and adjacent circuits.
