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...
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...
Microcontroller & Programmable Logic Controllers Write any six features of 8051 micro controller? All peripherals are integrated into a single chip, the overall system cost is very low. Simple to integrate in any electronic...
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...
