What else can I help you with?
What happened if the capacitor is in line when there is no load?
When there is no load on a circuit with a capacitor in the line, no current will pass. The capacitor, if charged, will remain charged until a load is put on to the circuit at which time it will discharge its designed output voltage.
How does a capacitor work in various industrial and domestic appliances and examples of capacitor in use?
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.
What is the environmental impact of having a transmission line connected close to your house?
You probably have a transmission line connected into your home. The environmental impact is virtually nill.
What is leakage current in underground transmission line?
The leakage current in underground transmission line are any two conductors separated by an insulating medium. It constitutes a condenser and a capacitor.
Why capacitors are not connected in series in power line?
capacitor's characteristic is charging and discharging. discharged energy will be dropped by load . so it is connected in parallel
Phase limit in induction furnace?
It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.
Why non directional relays are connected in sending end of transmission line?
relay:sensing device
What is surge impedance in power systems?
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.
What is a major advantage of having a compensated transmission line?
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.
Which line requires compensation?
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.
What is a smoothing capacitor?
A Smoothing Capacitor is a capacitor which helps to smooth out fluctuations that may exist on a power supply line.
Why capacitor used in transmission line?
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).
