What’s behind transformer field testing?

Andrés Tabernero García ; Unitronics Electric

Abstract

To prevent unexpected outages it is necessary to implement a field test programme. It has to be decided what tests should be performed and what information is expected to be obtained from these tests. This paper describes a common set of field tests on the basis of prescribed standards and years of field experience. Offline and on-line tests are described as well as their use in diagnosis and trending. The paper also highlights the importance of training in this process to make conclusions and recommendations reliable.
