Power transformer lifecycle: Transformer specification and sustainability

Jos Wetzer

Abstract

To secure the quality of the installed asset base, in this case power transformers, utilities and industries rely on quality assurance. This paper will focus on quality assurance in the early phases of the lifecycle, prior to operation. Elements contributing to this quality assurance are specification, design review, quality review of the manufacturer or production, and testing. The question will be addressed what quality assurance options are available and meaningful. Moreover, the paper presents specification as one of the possibilities of quality assurance and discusses the specification requirements and options in more detail.
These days, transformer requirements increasingly involve sustainability aspects. Such aspects may include the environmental impact, energy efficiency and losses, and the lifetime and recycle options of the materials. This paper will discuss how such sustainability aspects may be incorporated in the transformer specification, and reflect on present practice using experience from decades of projects worldwide.
