摘要：
Substantial benefits can be obtained by operating power transformers beyond current practices that are based on nameplate ratings and thermal algorithms that are general in nature and usually conservative. Extension of the useful life of power transformers is the single most important strategy for extending the life of power transmission and distribution infrastructures. This paper presents a survey of new monitoring and diagnostic technologies and applications, including laboratory experimental work, in power transformer insulation monitoring for the purpose of condition assessment.
