IEEE 665-1987

IEEE 665-1987 is a technical guide for generating station grounding, offering direction for grounding practice in power-generation facilities. It addresses the grounding considerations that help support safe operation, equipment protection, and reliable performance in station environments where electrical fault conditions and interference can affect systems. For engineers working in power, energy, and industry applications, this standard provides a focused reference for grounding-related design and review decisions.

What is IEEE 665-1987?

IEEE 665-1987 is the IEEE Guide for Generating Station Grounding, a document centered on grounding principles for generating stations and related electrical installations. Its purpose is to support consistent grounding design and evaluation where power equipment, control systems, and station structures must operate together safely. The guide is relevant to grounding layout, bonding practices, and the technical judgment needed to reduce hazards and unwanted electrical effects in a generation environment. IEEE 665-1987 is best used as a reference for planning and checking grounding arrangements.

Where is IEEE 665-1987 used?

This guide is commonly used in power-generating stations and other facility designs where grounding is a key part of electrical infrastructure. It is relevant to station grounding networks, associated switchgear areas, control rooms, and equipment that must remain properly bonded to manage fault current and interference concerns. In power, energy, and industry applications, IEEE 665-1987 may support engineering review, retrofit planning, and the coordination of grounding details across generation-related electrical systems.

Why is IEEE 665-1987 important?

Grounding is a core safety and performance issue in generating stations, and IEEE 665-1987 helps bring structure to that work. Using a dedicated grounding guide can support better design control, more consistent procurement requirements, and clearer technical expectations during installation or inspection. It may also help reduce risk by addressing grounding choices that affect personnel safety, equipment protection, and operational reliability. For organizations managing generation assets, IEEE 665-1987 provides a practical reference for grounded system decisions.
