The object of this Test Procedure is to establish a method for estimating by comparison the life expectancy of specialty transformer insulation systems under actual operating conditions. The electrical insulation of specialty transformers is made up of many different components selected to withstand the widely different electric, mechanical, and thermal stresses occurring in different parts of the structure. How long an insulation system will be serviceable depends on the effectiveness of the physical support for the insulation, and the severity of the forces acting on it, as well as on the materials themselves and the service environment. Therefore, the length of useful life of the insulation system will depend on the way that its individual components are arranged, their interactions upon each other, and the contribution of each component to the electrical and mechanical integrity of the system.

ST 259:2008 - For Television — SDTV1 Digital Signal/Data — Serial Digital Interface
January 29, 2008 - Society of Motion Picture and Television Engineers

This standard describes a 10-bit serial digital interface operating at 143/270/360 Mb/s. The serial interface may carry uncompressed SDTV signals, or data. This standard has application in the television studio over lengths of coaxial cable where the signal loss does not exceed an amount specified b...

259-1999 - IEEE Standard Test Procedure for Evaluation of Systems of Insulation for Dry-Type Specialty and General-Purpose Transformers
January 1, 1999 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A uniform method by which the thermal endurance of electrical insulation systems for dry-type specialty and general-purpose transformers can be compared is established. Covered are insulation systems intended for use in the types of transformers described in NEMA ST 1-1988 and NEMA ST 20-1992.

259-1994 - IEEE Standard Test Procedure for Evaluation of Systems of Insulation for Specialty Transformers
January 1, 1994 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A uniform method by which the thermal endurance of electrical insulation systems for dry-type specialty and general-purpose transformers can be compared is established. These insulation systems are intended for use in the types of transformers described in NEMA ST 1-1988 and NEMA ST 20-1992

259-1974 - IEEE Standard Test Procedure for Evaluation of Systems of Insulation for Specialty Transformers
January 1, 1974 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The intent of this standard is to establish a uniform method by which the life of specialty transformer insulation systems can be compared. Thermal degradation is generally one of the major factors affecting the life of most insulating materials. It was chosen to be the major environmental factor in...
