A worker may use a conducting wand during the approach to first make the connection. Once on the line, the worker is safe from shock as both the lineworker and the wire are at the same electric potential, and hence no current passes through their body. This is the same principle as that which allows birds to safely sit on power lines. [3]
This is typically not symmetrical across phases. By transposing, the overall capacitance for the whole line is approximately balanced. Transposing also reduce effects to communication circuits. [1] Wire transposition on top of pole. A transposing scheme is a pattern by which the conductors of overhead power lines are transposed at transposing ...
Arcing horns protecting bushings on a distribution transformer. Arcing horns form a spark gap across the insulator with a lower breakdown voltage than the air path along the insulator surface, so an overvoltage will cause the air to break down and the arc to form between the arcing horns, diverting it away from the surface of the insulator.

Overhead power lines are often equipped with a ground conductor (shield wire, static wire, or overhead earth wire). The ground conductor is usually grounded (earthed) at the top of the supporting structure, to minimize the likelihood of direct lightning strikes to the phase conductors. [ 17 ]
Aluminum wire requires a larger wire gauge than copper wire to carry the same current, but is still less expensive than copper wire for a particular application. Modern 500 kV overhead power lines used in an electrical power distribution system supplied by a utility
Transmission line cables require impedance matching to carry electromagnetic signals with minimal reflections and power losses. The distinguishing feature of most transmission line cables is that they have uniform cross-sectional dimensions along their length, giving them a uniform electrical characteristic impedance. Signal terminators are ...
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire ) to act as a ...
The first story arc, called "Whole Cake Island", adapts material from the rest of the 82nd volume to the beginning of the 90th volume of the manga by Eiichiro Oda. It deals with Luffy and his small team rescuing Sanji from his arranged marriage to finalize a political alliance between his own family, the Vinsmokes, and Big Mom's family.
