Response Guide: Understanding Underwater Electric Transmission Line Dielectric Oil Leaks

Addressing the underwater dielectric fluid leaks, this paper presents case studies and recommendations based on extensive response actions. Dielectric fluid leaks that occur underwater are significantly more challenging due to their dispersing properties in water which make these spills significantly more difficult to assess and cleanup. After distilling information from past case studies, it was determined that the success of a dielectric spill response depends on three variables: the amount of time until completion, damage to natural resources, and the cost. Although every incident poses its unique challenges and variables, this research highlights overarching best practices that can be applied to future spills. The analysis focuses on notification, discovery methods, sampling strategy, potential toxicity, effective clean-up strategies, and clean-up endpoints. The research concludes by acknowledging that these spills will be reoccurring until upgrades and increased maintenance is completed on aging U.S. electrical infrastructure.

INFLUENCE OF SUSPENSION OF WIRES ON THE ELECTROMAGNETIC FIELD OF A HIGH-VOLTAGE ELECTRIC TRANSMISSION LINE

The conditions of electromagnetic safety on the route of a high-voltage power line are considered, taking into account the sag of the wire. As a result of modeling in the Fazonord software package, it was shown that taking into account the sag of the power line wire causes a significant change in the electric and magnetic fields at a normalized height

Mathematical Modelling of Drive System with an Elastic Coupling Based on Formal Analogy between the Transmission Shaft and the Electric Transmission Line

In the paper, the kinematic structure of the transmission shaft between the driving motor and the working mechanism is studied. The analysis is based on electrical and mechanical similarities. The equivalent circuits, typical for electrical systems, are defined for the transmission shaft concerned. Modelling of the transmission shaft based on a formal analogy between the transmission shaft and the electric transmission line is also proposed. The results of a computer simulation and experimental test are presented. The results confirm the high conformity of the proposed mathematical model with the physical object.
