TL;DR: In this paper, a consistent laboratory reproduction of waveforms during impulse tests with solid insulation materials has been a difficult task, and carbon polyethylene composites can serve as benchmarks for such studies.
Abstract: A consistent laboratory reproduction of waveforms during impulse tests with solid insulation materials has been a difficult task. Carbon polyethylene composites can serve as benchmarks for such studies. Experimental results on films and a practical voltage transformer (VT) are shown that can help develop signal analysis tools.

TL;DR: In this paper, the use of concurrent UHF antenna and winding currents was proposed to locate breakdown in dry-type transformers, and the work can be extended to identify partial discharge events in dry type transformers.
Abstract: Changes in resonant frequencies of a winding can identify the location of breakdown during impulse tests. This is difficult with a uniform winding. We propose the use of concurrent UHF antenna and winding currents in order to locate breakdown. The work can be extended to identify partial discharge events in dry type transformers.
