IEEE Std C62.82.1-2010 PDF

Full title and description

IEEE Std C62.82.1-2010 — "IEEE Standard for Insulation Coordination — Definitions, Principles, and Rules." The standard defines principles and rules for insulation coordination and specifies procedures for selecting equipment withstand voltages (basic lightning impulse insulation level, BIL, and basic switching impulse insulation level, BSL). It also identifies a set of standard insulation levels for equipment insulation systems used on three‑phase AC systems.

Abstract

Provides definitions, principles and calculation rules for insulation coordination applied to equipment insulation systems. The document presents a procedure to select phase‑to‑ground and phase‑to‑phase withstand voltages and lists standard insulation levels based on expected voltage stresses. The standard is a revision of IEEE Std 1313.1‑1996 and is complemented by an application guide (IEEE C62.82.2).

Scope

The standard specifies the procedure for selecting withstand voltages (BIL and BSL) for equipment phase‑to‑ground and phase‑to‑phase insulation systems and provides a list of standard insulation levels keyed to the expected voltage stress. It applies to three‑phase AC systems (IEEE record shows applicability to systems above distribution‑class voltages; IEEE materials describe application to three‑phase AC systems above 1 kV with other summaries referencing higher voltage bands). The standard's principles are applicable to various air‑insulated equipment and systems; a companion guide (IEEE C62.82.2) offers application examples and calculation methods.

Key topics and requirements

• Definitions and terminology for insulation coordination (BIL, BSL, withstand voltages, surge/stress categories).
• Procedure and rules for selecting equipment basic lightning impulse insulation level (BIL) and basic switching impulse insulation level (BSL).
• Tables and lists of standard insulation levels for equipment based on voltage stress and system class.
• Principles for correlating equipment insulation to system overvoltages and recommended coordination practices.
• Cross‑references to application guidance (IEEE C62.82.2) and related insulation coordination guides.

Typical use and users

Used by power system engineers, substation and transmission designers, equipment manufacturers (transformers, switchgear), protection and grounding engineers, testing laboratories, and consultants performing insulation coordination studies and selecting surge arresters and insulation levels for medium‑ and high‑voltage equipment. The standard is used as a technical reference when establishing BIL/BSL values and standard insulation classes for three‑phase AC equipment.
