Routine and Design tests • Routine tests shall be made on every transformer to verify that the product meets the design specifications. • Design tests shall be made on a transformer of new design to determine the adequacy of the design of a particular type, style or model of transformer or its component parts. • Other tests are identified in individual product standards and may be specified by the purchaser in addition to routine tests.
Insulation levels • Class I power transformers shall include power transformers with high-voltage windings of 69kV and below. • Class II power transformers shall include power transformers with high-voltage windings from 115kV thru 765kV.
