Network composite insulators for overhead lines: disconnecting due to unidentified reasons

Design and selection criteria for HVDC overhead transmission lines insulators

Postoperative delirium: disconnecting the network?

214 August 2014 N ETWORKS are central to life, a fact that becomes strikingly apparent when they become dysfunctional. We have all experienced a sense of frustration when the “net is down” or when trapped in an airport because some critical hub in another city has been debilitated by an unexpected snowstorm. Even seemingly minor disruptions in the transfer of information or people can lead to a...

Mechanical Design of Overhead Lines

8.17 Some Mechanical Principles Introduction Electric power can be transmitted or dis tributed either by means of underground cables or by overhead lines. The underground* cables are rarely used for power transmission due to two main reasons. Firstly, power is generally transmitted over long distances to load centres. Obviously, the installation costs for underground transmission will be very h...

Connecting and disconnecting nematic disclination lines in microfluidic channels.

Disclination lines in nematic liquid crystals can be used as "soft rails" for the transport of colloids or droplets through microfluidic channels [A. Sengupta, C. Bahr and S. Herminghaus, Soft Matter, 2013, 9, 7251]. In the present study we report on a method to connect and disconnect disclination lines in microfluidic channels using the interplay between anchoring, flow, and electric field. We...

Composite insulators and their aging: An overview

The aging (biological deterioration) is a major problem of composite insulators now-a-days. The main thing in aging is to predict how, when and with what speed it occurs and under what conditions it can lead to failure and what overall average expected life of a composite insulator is. For this a lot of researches have been done. This review summarizes the methods of artificial field testing (a...
