Voltage Surge or Transient Voltage: A sudden rise in voltage for a very short duration on the power system is known as a Voltage Surge or Transient Voltage. Transients or…
Principle of Vacuum Circuit Breaker: In the Principle of Vacuum Circuit Breaker, vacuum (degree of vacuum being in the range from 10-7 to 10-5 torr) is used as the arc quenching…
Short Circuit in Power System: Whenever a fault occurs on a network such that a large current flows in one or more phases, a Short Circuit in Power System is…
Overhead vs Underground System: The distribution system can be Overhead vs Underground System. Overhead lines are generally mounted on wooden, concrete or steel poles which are arranged to carry distribution…
Underground Cables: Electric power can be transmitted or distributed either by overhead system or by underground cables. The underground cables have several advantages such as less liable to damage through storms…
Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
Types of Insulators in Transmission Lines: The overhead line conductors should be supported on the poles or towers in such a way that currents from conductors do not flow to…
Line Support: The supporting structures for overhead line conductors are various types of poles and towers called line support. In general, the line supports should have the following properties :…
