Abstract

Precision measurements of transformer insulation quality demands minimizing damage during test-to-breakdown. A fault tolerant insertion system has been developed for this application. This paper addresses a current limiting model for this system design that protects the high current insertion transformer from sustaining irreparable damage. The autotransformer is a transformer with a single winding that is tapped at intervals rather than having multiple windings
