What is the physical meaning of characteristic impedance?

The characteristic impedance is the ratio of wave voltage to wave current at each point along the line. Physically, the characteristic impedance depends on the cross-sectional geometry of the line, which controls the shunt capacitance per unit length, and the series inductance per unit length of the line.

Why is surge impedance important?

Surge Impedance Loading is a very essential parameter when it comes to the study of power systems as it is used in the prediction of maximum loading capacity of transmission lines.

What is the meaning of the word surge ‘?

1 : to rise and fall actively : toss a ship surging in heavy seas. 2 : to rise and move in waves or billows : swell the sea was surging. 3 : to slip around a windlass, capstan, or bitts —used especially of a rope. 4 : to rise suddenly to an excessive or abnormal value the stock market surged to a record high.

What is physical significance of intrinsic impedance?

Intrinsic impedance describes the magnitude of the magnetic and electric fields present in the free space. The derivation of the intrinsic impedance of any uniform medium is dependent on the permittivity and permeability of the medium. When the conductivity of the medium varies, the intrinsic impedance also changes.

What is lossy and lossless transmission lines?

A lossy transmission line consists of an appreciable value of series resistance and shunt conductance where different frequencies travel at different speeds. This is opposite to a lossless transmission line, where the speed of wave propagation is the same for all frequencies.

What is surge impedance loading Sil?

Surge Impedance Loading (SIL) Surge impedance loading (SIL) of a transmission line is the MW loading of a transmission line at which natural power balance occurs. The following brief article explains the concept of SIL. Transmission lines produce reactive power (MVar) due to their natural capacitance. The.

What is the surge impedance of a transmission line?

The characteristic impedance or surge impedance (usually written Z0) of a uniform transmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of reflections in the other direction.

What type of word is surge?

surge used as a noun: A sudden rush, flood or increase which is transient.
