Superconducting Power Transmission Lines Cost Assessment
1990A computer model of the component costs of superconducting power transmission lines (SPTL) has been prepared by Brookhaven National Laboratory (BNL) for the Empire State Electric Energy Research Corporation (ESEERCO). Technical design requirements from the work of Brookhaven and Los Alamos National Laboratories have been reviewed for low Tc cables ...

Power line communication using timed transmission
2003 International Symposium on VLSI Technology, Systems and Applications. Proceedings of Technical Papers. (IEEE Cat. No.03TH8672), 2004This paper reviews established methods of communication using in-building power conductors with particular attention to the 100 kHz to 450 kHz frequency range. It also reviews line characteristic impedance and it presents new measurements of attenuation and noise on the power conductors.

Modelling of power transmission line components
2020The aim of this chapter is to present and discuss models of power transmission line components for the calculation of lightning overvoltages on transmission lines due to direct lightning strikes. The models presented in this chapter are based on lumped- and distributed-circuit theory.

Wataynikaneyap Power Transmission Line Infrastructure Exposé
2022This project is an infrastructure exposé documenting the Wataynikaneyap Power Transmission Line. The piece discusses the potential for an apparently responsible infrastructure to be used to power destructive ones in the future and asks what the moral and environmental implications may be.

Power transmission line modeling-a comparison
Proceedings of 40th Midwest Symposium on Circuits and Systems. Dedicated to the Memory of Professor Mac Van Valkenburg, 2005This work discusses the performance of two transmission line approximation methods for real time digital simulation. The comparison uses case studies in time and frequency domain relating approximation results to the integration time step.

ULTRA HIGH POWER TRANSMISSION LINE TECHNIQUES
1963Abstract : The ultra-high power transmission line techniques including both failure mechanisms and component design are discussed. Failures resulting from localized regions of heated gas were studied and a more general equation for breakdown was derived to show the effect of the size of the region.

Refurbishing the supergrid power-transmission lines
Electronics and Power, 1982The supergrid, constructed in the late 1950s and 1960s is in need of refurbishment and upgrading. What methods will be used for this major operation?

Life lines [power transmission system maintenance]
Power Engineer, 2005The transmission system in England and Wales has more than 7000 route-km of overhead lines, typically operating at 275 kV and 400 kV. It sounds impressive, but the number of lattice steel towers totals 22,000. Now owned and operated by National Grid, the bulk of the 275 kV network was built in the early to mid 1960s, while the 400 kV network was ...
