Transformer maintenance: Health indices and life assessment methodology
Marius Grisaru
Abstract
Nowadays, trendy attempts to avoid transformer failures include life assessment programs, software and health indices. Although many efforts are invested in these approaches, the transformer failure rate is not significantly reduced. This article will highlight the main critical points that have to be taken into consideration when index and life assessment is concepted and evaluated. The more details are taken into consideration and the more deeply they are treated, the more representative and accurate the health index will be. An accurate health index is probably the best maintenance strategy to have for a large transformer fleet, and it may be ingrained in the mind of any human interdisciplinary expert, or in the code of an artificial intelligence software.
