Capacitors can be used to decrease the inductance of power lines (series compensation), and for voltage support (capacitors are put in parallel with the system).
yes.
The leakage current in underground transmission line are any two conductors separated by an insulating medium. It constitutes a condenser and a capacitor.
Actually surge impedance is present in a transmission line due to the capacitance of transmission line. Now this capacitor attends the reactive power of the transmission line to energise its magnetic flux. now due to the flux the impedance will increase and the power is reactive too. due to the impedance loss is more.
The advantage of having a series compensated line is that it corrects for undervoltages created when a line is overloaded and acts as an inductive element. To compensate for this a series capacitor is added to produce the extra Vars being absorbed by the overloaded line. This will create a smoother voltage profile across the transmission line.
Basically an AC transmission line require compensation in terms of reactive power. To push the active power across a transmission line certain amount of reactive power is necessary. In AC transmission line reactive power is generated and consumed. Generator is responsible for the production of reactive and active power both. Than this reactive power is consumed by the load and transmission line. Additional reactive power s supplied by the capacitor. This extra power supplied by the capacitor is termed as reactive power compensation. Requirement of this reactive power is there because reactive power is necessary to maintain the voltage stability.
The capacitor symbol looks like: --|(--
mho rerlay is used in long transmission lines
IR transmission type of transmission is used in television system .
A Smoothing Capacitor is a capacitor which helps to smooth out fluctuations that may exist on a power supply line.
There are three types of transmission lines of India given follows ---- 1-long transmission line( which is used grid to power suppliers plant ) 2-medium transmission line ( which is used power supplier plant to the industry ) 3- short transmission line ( which is used transformer to the consumers )
by using capacitor on the line we can reduce spike current or we can use a capacitor bank for the rated line capacity.
Capacitor is connected parallel to the line which serves as power factor correction, increase line efficiency, voltage stability and reduced line losses and voltage drop.
