Transmission Line Charging
To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
What else can I help you with?
Name the two basic types of transmission line which is most widely used?
coaxial cable and twisted pair cable. coaxial cable is the most widely used type of transmission line.
What is Serial line interface protocol?
It is a very simple protocol used for transmission of IP datagrams across a serial line.
What is the main limitation of microwave transmission?
The main limitations to Microwave transmission is the fact that it needs line of sight and that it can be subject to interference such as planes passing over, or rain
What i the similarities between charging by conduction and charging by induction?
conduction charging is a kind of charging that the electrical loud must plug in to a power source like electric city or power supply or an adaptor. but induction charging is a way to charging a electrical loud that in this way electrical energy induces to our load throw magnetic field
Advantage and disadvantage of corona of transmission line?
advantages:due to corona formation the sir surrounding the conductor becomes the conducting and hence virtual dimeter of the conductor is increased.
What is charging current in transmission lines?
Any two conductors separated by an insulating medium constitutes a condenser or capacitor.In case of overhead transmission lines, two conductors form the two plates of the capacitor and the air between the conductors behaves as dielectric medium. Thus an overhead transmission line can be assumed to have capacitance between the conductors throughout the length of the line. The capacitance is uniformly distributed over the length of the line and may be considered as uniform series of condensers connected between the conductors.When an alternating voltage is applied across the transmission line it draws the leading current even when supplying no load. This leading current will be in quadrature with the applied voltage and is termed as charging current. It must be noted that charging current is due to the capacitive effect between the conductors of the line and does not depend on the load. The strength of the charging currents depends on the voltage of transmission, the capacitance of the line and frequency of the ac supply. It is given by the expressionSignificance of Charging currents:Capacitance effect (responsible for charging currents) of the short transmission lines are negligible. However they are significant in medium and long distance transmission lines.In long distance transmission lines, during light loaded conditions receiving end voltage will be higher than sending end voltage. This is because of the charging currents and capacitive effect of the line
How do you change transmission line?
how to fix a transmission without taking it a part how to fix a transmission line
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
Is there one coolant line or two for the transmission on a 98 Mercury?
If this vehicle has a transmission cooler then it will have one line to the cooler then another for the return line to the transmission.
Will low pass filter works as transmission line?
No, but transmission line act as a lpf
What is A in the nominal pi model of transmission line?
balanced pi model for a long transmission line.
How do you replace Impala transmission line?
how much to replace the transmission line in 2006 Chevy impala
Why capacitance is neglected in short transmission lines?
Wen the length of overhead transmission line is less than 80 km with an operating voltage up to 20kv it is considered as short transmission lines Due to smaller lengths and low operating voltage the charging current is low so the effect of capacitance of short transmission lines is extremely small and therefore can be neglected as in case of distribution lines and only R L is to be taken into account while analyzing short transmission lines
What is full form of DCDS transmission line?
Double Circuit Double Circuit String Transmission Line
What transmission line is located in the front of a dodges transmission?
pressure
What are the secondary constant of transmission line?
The secondary constants of a transmission line are the surge impedance, propagation constant, attenuation constant, and phase constant. These constants determine the behavior of signals traveling through the transmission line and are important for analyzing the performance of the line in terms of signal integrity and power transmission.
What is pg clamps in transmission line?
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
