Under Ground Cables An Under Ground Cables essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. Under Ground Cables are used, where it is impractical to...
An Under Ground Cables essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. Under Ground Cables are used, where it is impractical to use overhead line...
Types of insulators used in AC distribution system. Overhead line conductors should be supported on the poles or towers with the help of insulators. The insulator provide necessary insulation between the line conductors and...
Voltage regulation When transmission line carries the current, there is a voltage drop in the line due to resistance and inductance of the line. This results, the receiving end voltage VR is less than...
Explain methods of AC distribution system based on connection scheme. The following connection schemes of distribution system are generally employed: Radial System: In a radial system, separate feeders radiate from a single sub-station and feed the...
Particular AC Transmission system DC Transmission system Definition The AC transmission line transmit the alternating current. The DC transmission line transmit the Direct current. No of conductors used Three Two Inductance & Surges Have...
Explain the effect of wind and ice coating on overhead transmission lines. When the transmission line is coated with ice and simultaneously subjected to wind pressure, the thickness and size of the conductor increases....
Express the calculation of Sag in equal and Unequal levels In an overhead line, sag should be so adjusted that tension in the conductors is within safe limits. The tension is due to the...
