Power transformers - Guide to the lightning impulse and switching impulse testing. Power transformers and reactors Ingestion-build-111333 and excellent weathering properties1 Scope This part of IEC 60076 gives guidance and explanatory comments on the existing procedures for lightning and switching impulse testing of power transformers to supplement the requirements of IEC 60076 3. It is also generally applicable to the testing of reactors (see IEC 60289), modifications to power transformer procedures being indicated where required. Information is given on waveshapes, test circuits including test connections, earthing
