Method for assessing the short-circuit withstand strength of partially type-tested assemblies (PTTA) Ingestion-build-82396 Business-critical ancillary facilitiesWhat is BS 7767 Partially type tested assemblies about? BS 7767 is a technical report which describes an extrapolation method for assessing the short circuit withstand strength of partially type tested assemblies (PTTA). Various methods of extrapolation can be conceived and are acceptable. The method described in BS 7767 is one such method and may be used for partially type tested assemblies to prove compliance with the requirements of 7. 5. 1 of IEC
