Abstract

This Uganda Standard applies to power transformers as defined by and in the scope of US IEC 60076-1. It gives details of the applicable dielectric tests and minimum dielectric test levels. Recommended minimum external clearances in air between live parts and between live parts and earth are given for use when these clearances are not specified by the purchaser. (This Uganda Standard cancels and replaces US EAS 371-3:2005, Specification for power transformers - Part 3: Insulation levels and dielectric tests, which has been technically revised).
