Types of Tower

-

Tower:

The structure which are used to support the transmission lines are called tower or line support poles.

The types of Tower are following:

1.) Wooden poles: 

Wooden poles are used for low voltages and distribution purpose only. Wooden poles are used for line Voltage upto 11 kV.

2.) Reinforced concrete poles:

These poles are mechanically strong and their mantainance cost is low. Their life is very long but these tower are very heavy. Hence, the cost of transportation is high. These are used for system upto 33 kV voltage levels.

3.) Steel Tabular poles:

These towers are designed for high and extra high voltage transmission line for longer life such poles must be painted regularly.

4.) Lattice steel Poles:

This steel towers are very commonly used as these are suitable for the system with voltage higher than 33Kv and useful for long span. These are useful for railway line crossing; river crossing and crossing of valleys.

Reactive Power

Reactive Power Reactive power is used to control voltage over transmission line or in power systems network. Mathematically, Reactive Power is product of volage and current with sin(phi).        Q = VI sin(phi) -----------(1) Here, we observed that from eq.(1), Reactive Power depends upon flux (phi). And We have,   V = E1 = 4.44 Nf(phi) ----------(2)     Where, phi = magnetic flux(Weber)                     N  = No. of turns                     f   = freuency(Hz) From eqn(2), We can says that, voltage depend upon flux. By this way we can say that, Reactive Power depends upon voltage. In case of synchronous machine: Over excitation ---> Over flux ---> Over R.P Need of Reactive Power : Voltage control in power system is important for proper operation for electrical devices/elements to prevent from damage such as :  -To reduces Transmission lines losses -To mantain the ability of system and prevent Voltage collapse. -Over heating of Electrical machine - Reactive Power (VARs) is used

Surge impedance Loading

Surge Impedance Loading: A transmission line may considered as generating capacitive reactive volt-amperes in shunt capacitance and consuming (absorbing) inductive reactive volt-amperes in its series inductance. The load at which inductive and capacitive reactive volt amperes are equal and opposite is called the surge impedance Loading or (nature load of the line). "The power delivered by the line to purely resistive load equal to its surge impedance the load at which the inductive and capacitive reactive volt-amperes are equal and opposite, is called surge impedance Loading of the line." Capacitive volt-amp. generated in the line = V *I = V / Xc = V² / ωL Inductive volt-amp.  absorbed in the line = V * I = I *XL = I² *ωL Under natural load conditions, Capacitive volt-amp. = Inductive volt-amp.             V² * wc   =    I² * ωL    or,  V / I   = √(L/C) =  Zo = Surge impedance At this load V and I are in same phase. At this Zo is purely resistive. There is not present imagina

Ferranti Effect

 When Recieving end of the transmission line is operating under no load condition or lightly condition,sending end voltage(Vs) is less than Recieving end Voltage (VR). Ferranti Effect is due to charging current Ic of the line. In medium Transmission lines; At No-Load,   Hence, Recieving end Voltage is more than sending end voltage. This is Ferranti Effect. This is also show that Ferranti Effect depends on the frequency and Electrical Length of the line. Now Let's see; At Load condition, Here, we saw that, No Ferranti Effect occurs at Load condition. **Ferranti Effect is more dominanting in communication Lines.** ## Elimination of Ferranti Effect: --To eliminate/nullify Ferranti Effect, we need inductor parallel to the capacitor.
