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

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
Why transmission lines are thicker than TV cable wires?
Transmission lines are thicker than TV cable wires because the transmission lines are used to transmit both low freq and high freq signals. And the losses of the transmission lines depend the resistance of the line which inturn depend upon length and area. As we have to transmitt the signals over long distances the transmission lines are thicker in size.Whereas in TV cable wires the construction is totally different in which transmission of signals is in between two conductors thereby avoiding losses.Therefore there is no necessity for these lines to be made thicker. That is why transmission lines are thicker than TV cable wires.
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

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.

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
