IEEE C62.11-2020 Test Changes
ArresterFacts 050 Understanding Changes IEEE C62.11 2020

Revision 2020 to IEEE C62.11 revises the required tests to contain more realistic requirements while at the same time harmonize it with the equivalent IEC standard 60099-4. ArresterFacts 050 is an outline of the revisions in a manner that makes them more understandable and easier to implement by all stakeholders.
