Full title and description

IEC TR 62655:2013 — Tutorial and application guide for high-voltage fuses. This technical report provides an informative tutorial on the construction, operation and application of high-voltage fuses rated above 1 kV a.c., including current-limiting, expulsion, electronic and other non-current-limiting types, and discusses regional application practices.

Abstract

Informative technical report (tutorial) explaining the principles, design features and application considerations for high-voltage fuses. It describes different fuse types, their operating behaviour, selection criteria, typical applications and regional practices (North American, European and others). The document contains explanatory material only and does not set normative requirements.

General information

• Status: Technical Report (informative)
• Publication date: 22 May 2013

Scope

Provides background and application guidance for high-voltage fuses rated above 1 kV a.c. The report covers fuse construction and operating principles, characteristics of current-limiting and non-current-limiting fuses (including expulsion and electronic types), selection and application practices, operational behaviour under fault conditions, and regional installation practices and considerations. As a Technical Report, it is informative and intended to support understanding and correct application rather than prescribe mandatory requirements.

Key topics and requirements

• Overview of high-voltage fuse types (current-limiting, expulsion, electronic and other non-current-limiting designs)
• Construction, materials and internal operation of fuses used above 1 kV a.c.
• Operating characteristics and interruption behaviour under short-circuit and overload conditions
• Selection criteria for system coordination, rating and fault clearing
• Installation and application practices in different regions (North America, Europe and others)
• Safety considerations, mounting and protective arrangements
• Illustrative examples, explanatory diagrams and application guidance (informative)

Typical use and users

Used as a reference and training/tutorial resource by electrical engineers, power-system designers, protection engineers, fuse manufacturers, testing laboratories, utilities and consultants who need to understand fuse behaviour, selection and application in high-voltage systems. Also useful for standards developers and technical instructors as background material.

Related standards

Commonly referenced alongside standards in the high-voltage fuse and protection family such as the IEC 60282 series (high-voltage fuses) and other IEC publications addressing coordination and switchgear protection practices; national standards and utility guides on fuse application and system protection may also be relevant.
