4.3 Transmission Line Structures The primary function of a transmission line structure is to support the transmission lines. The design of the transmission line structure must consider environmental conditions, area requirements, voltage levels, and right-of-way (ROW) requirements. The ROW is the amou...
Automatic identification of voltage levels during climbing the tower close to high voltage lines is important for the safety of electric construction workers. According to the characteristics of the electric field distribution of different voltage levels of the transmission line, the electric field sensor...
This invention provides very wide channel, open drain, N- channel CMOS drivers and cascode CMOS receivers for interfacing VLSI CMOS circuits to transmission lines which are terminated by their characteristic resistive impedances to voltage levels on the order of about 1.2 v-2.0 v. These GTL (a ...
about 2,000 kilometers away. The new link is able to meet the electricity needs of about 24 million people, and sets a new benchmark in terms of voltage levels and transmission capacity, superseding the 600 kV (kilovolt) Itaipu transmission line in Brazil, which was also delivered by ABB...
In this chapter, the discussion on jitter is limited to the context of DRAM memory systems with digital voltage levels, and only the short-term phase variations that exist between successive cycles of a given signal are considered. For example, electronic components are sensitive to short-term ...
输电线路外文翻译文献An Investigation into Extreme-Weather- Caused Transmission Line Unavailability 1 Abstract -- One of the primary causes of major transmission line outages is extreme weather conditions particularly lightning, wind and conductor icing (e.g., Quebec, U.S. ice storms of 1998). ...
The minimum acceptable gap setting of an EGLA is determined by three factors: the system voltage, expected temporary overvoltage levels (TOV), and a safety factor (K). The minimum AC power frequency voltage that EGLA gap will flashover is: (7)where V is minimum power frequency flashover ...

The power transfer capability of the transmission line is directly proportional to the square of the voltage and inversely proportional to the impedance of the transmission line. The impedance of transmission lines operating at different voltage levels decreases with the increase in voltage, but such ...
