Stretching 2,080 kilometers, the ±800 kV ultra-high voltage direct current transmission line between southwest China's Sichuan Province and east China's Jiangsu Province spans the Yangtze River here in Anhui. As a critical part of China's west-to-east power transmission project, this line ann...
In a system where a number of transmission lines are fed from a common source, the phase relationship at the far end of the lines is determined by the electrical length of the transmission lines. This length is a function of the physical length and the dielectric constant of the line. Any...
Thetransmission linegoes as per available corridors. Due to the unavailability of the shortest distance straight corridor transmission line has to deviate from its straightway when obstruction comes. In the total length of a long transmission line, there may be several deviation points. According to ...
The foundation of any structure is crucial for its safety and performance as it transfers mechanical loads of theelectrical transmission systemto the ground. A transmission tower cannot function properly without a sound foundation. Foundations must be designed to match the specific soil conditions where...
also can manufacture the products that are based on BS and other standards.In addition,under customers' requirement,we can design and manufacture the products that have special performance.The power cable are used in fixed laying on transmission and distribution electrical lines of 50HZ AC rated...
where r is the radius of the armature conductor about the centre of rotation, Ia is the current flowing in the armature conductor l is the axial length of the conductor, and Bav is the average flux density under a pole. Note that Bav=ϕ(2πrl)/2p The resultant torque per conductor is...
The miniaturization of metal–oxide–semiconductor field-effect transistors (MOSFETs) has been the driving force behind the development of integrated circuits over the past 60 years; however, owing to short channel effect, reducing the gate length of MOSFETs to sub-10 nm represents a fundamental ...
ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium (E.C.GRADE). Application Widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure...
of the transmission line. During GNSS operation, all substations can estimate the time of flight by correlating the received chirp with a time-synchronised local copy. During GNSS outage, time sychronisation to the central substation is maintained by correcting for the precalculated time of flight...
In this paper, we present an approach to model the transfer function of electrical power lines for broadband power line communication. The assuming channel consists of three wires, which is widely used in many countries. As an application of the proposed method, the effect of line length from ...
