The relevance of the problem is justified and review existing methods for determining overhead line sag by period conductor owned oscillations conducted. method controlling its own briefly presented. experimental installation conducting full-scale tests described, which includes (64 m), rigid fasteners at points suspension, accelerometer, temperature sensor mounted on conductor, data from are p...

We consider a convex polygonal heat conductor whose inscribed circle touches every side of the conductor. Initially, the conductor has constant temperature and, at every time, the temperature of its boundary is kept at zero. The hot spot is the point at which temperature attains its maximum at each given time. It is proved that, if the hot spot is stationary, then the conductor must satisfy two...

 When an alternating electric current flows through a conductor (wire), Electric-E and Magnetic-H fields are created around the conductor.  If the length of the conductor is very short compared to a wavelength (<< λ/4), the electric and magnetic fields will decrease dramatically within a distance of one or two wavelengths.  However, as the conductor is lengthened, the intensity of the fields...

Conventional ACSR conductors are formed by stranding aluminum wires over a steel core. The core does not contribute to current carrying and is used only for purposes. has great role in the shedding of line weight. With increase weight, longer poles at shorter distances, but it cannot be abandoned because undertakes transport task. Nowadays, search alternatives conventional conductor accelerated...

Solder ball height inspection is essential to the detection of potential connectivity issues in semi-conductor units. Current ball height inspection tools such as laser profiling, fringe projection and confocal microscopy are expensive, require complicated setup and are slow, which makes them difficult to use in a real-time manufacturing setting. Therefore, a reliable, in-line ball height measu...

In p r es e nt d a y mod e r n wor l d Vehicles have become an part and parcel of every one's life. Situations and circumstances have their predominant role in the usage of vehicles in this modernized urban life. As to consider both sides of the coin, this has its own effects, one of the main side effects being air pollution. Each and Every vehicle will have emission but the main problem occurs...

Overhead transmission lines are influenced by different factors which are mostly electrical and mechanical. These factors can cause problems for lines, distortions in network and outage of line. In designing transmission lines mechanical properties are evaluated after selecting a suitable conductor and clearance with regard to electrical properties. In lines designing, an important mechanical p...
