Sag in Transmission Line: The difference between in level between points of supports and the lowest point on the conductor is called Sag. The horizontal distance between two electrical supports is called the span. When...

ACSR (Aluminium Conductor Steel Reinforced): Due to low tensile strength, aluminium conductors produce greater sag. This prohibits their use for larger spans and makes them unsuitable for long distance transmission. In order to increase...

Line supports: The supporting structure for overhead line conductors are various types of poles, towers called Line supports. Properties of Line supports: High mechanical strength. Light in weight without loss of mechanical strength. Low...

Draw the schematic diagram of Distributor-Feeder-Service mains The part of power station. Which distributes electric power for local use is known as Distribution system. It consists of Feeder, Distributor, and the service mains. Feeder...

Compare Overhead and Underground transmission system Particular Over head system Under ground system Public safety Less safe More safe Initial cost Less expensive More expensive Faults Fault occur frequently very rare chance of fault...

Advantages of High Transmission Voltage: Reduce the volume of conductor material. Reduce the transmission conductor cost. Decreases the percentage line drop. Increase the transmission efficiency. (i) Reduces volume of conductor material: Consider the transmission of...
