Diagnosis of abnormal temperature rise observed on a 275 kv oil-filled cable surface: a case study [PDF]
, 2019 This paper presents a case study on a 275 kV oil-filled cable. The condition assessment and diagnosis are based on analysis of cable surface temperature in relation to its current load and insulation dielectric loss.

An equivalent circuit for the evaluation of cross-country fault currents in medium voltage (MV) distribution networks [PDF]
, 2018 A Cross-Country Fault (CCF) is the simultaneous occurrence of a couple of Line-to-Ground Faults (LGFs), affecting different phases of same feeder or of two distinct ones, at different fault locations.

The Earth System: An Introduction to Earth Systems Science [PDF]
Eos, Transactions American Geophysical Union, 1999 The atmosphere, hydrosphere, biosphere, and solid Earth are the basic components of the Earth system. These different components are not separate entities; instead they interact over a broad range of spatial and temporal scales. Determining how various internal and external influences impact each component of the Earth system individually is ...

The treatment of thin wire and coaxial structures in lossless and lossy media in FDTD by the modification of assigned material parameters [PDF]
, 2006 It has been shown recently that the use of modified assigned material parameters (MAMPs) within the finite-difference time-domain (FDTD) method provides a systematic, readily extensible, accurate, and efficient approach to the electromagnetic analysis of
