Estimation of Transformers Health Index Based on the Markov Chain

Energies, 2017
This paper presents a study on the application of the Markov Model (MM) to determine the transformer population states based on Health Index (HI). In total, 3195 oil samples from 373 transformers ranging in age from 1 to 25 years were analyzed.

Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]

The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.

An assessment of tailoring of lightning protection design requirements for a composite wing structure on a metallic aircraft [PDF]

The Navy A-6E aircraft is presently being modified with a new wing which uses graphite/epoxy structures and substructures around a titanium load-bearing structure. The ability of composites to conduct electricity is less than that of aluminum.
