1. Dielectric Response and Partial Discharge Diagnostics of Insulation Systems by Utilizing High Voltage Impulses
Abstract : In this thesis, power system transients are considered as an opportunity for development of on-line diagnostics of power components and specifically the insulation systems of power transformers and bushings.A new technique for on-line dielectric response measurement of power transformer bushings is proposed which utilizes natural transients in the power system, such as lightning and switching surges, as stimuli.

2. Pulsed holographic interferometry for the study of bending wave propagation in paper and in tubes
Abstract : Pulsed Holographic Interferometry (HI), is used to record propagating transient bending waves in plates and shells. These waves are generated mechanically by impact of a small steel sphere or optically by focusing a high energy laser pulse at the surface of the tested object. READ MORE
