Standard

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 this standard. Other environmental factors, such as vibration, thermal shock, and moisture, have been included to simulate operating conditions. These factors have been chosen in such a way as to develop and disclose promptly any significant weaknesses during the temperature aging of an insulation system. This standard is offered as a guide for preparing samples, conducting tests, and analyzing results. It provides a statistical method for establishing a life-temperature relationship of an insulation system and is intended to be an evaluation test, and not a production inspection or acceptance test.<>

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.
