Title :
Impulse Test Requirements for Generator Transformers and for Tertiary Windings
Author :
Bellaschi, Peter L.
Abstract :
The primary windings of generator transformers in general and tertiary windings in most applications are exposed to lightning indirectly or practically are unexposed. For these windings, the usual chopped-wave and full-wave impulse tests will suffice. Front- of-wave impulse tests are not justified in these applications.
