WITNESS FACTORY ACCEPTANCE TESTING (FAT)

The FAT is a well-defined set of performance tests that are to be performed for each transformer.  The industry standards, IEEE Standards, and the client specification are normally used as the body of information that defines the required tests and the acceptance criteria.  The witness of the FAT is a routine activity for JBTC.

The FAT may be witnessed in its entirety or for a portion of the tests.  It is very common for the client to request witness of the thermal performance test and dielectric tests only.  If this is the case, the JBTC practice is to review all other test data to ensure compliance to guaranteed values as well as adherence to all acceptance criteria.  Mr. Templeton has observed and witnessed hundreds of transformer tests for both shell form and core form transformers.  Mr. Templeton also has an extensive background in the analysis of test anomalies and test failures.
