the fault in electrical transmission line which give rise to symmetrical fault current is called symmetric fault. e.g; L-L-L-G fault. the fault in transmission line which give rise to unsymmetrical fault current is called unsymmetrical fault.e.g; L-L , L-L-G , L-G fault to solve the unsymmetrical fault, the fault current can be represented by sum of the sequences--zero phase sequence , +ve phase sequence , -ve phase sequence. where L:line G:ground

A two-port network is symmetrical if?
if AD-BC=1
What is symmetrical fault in transmission line?
A symmetrical fault is a fault where all three phases are experiencing the same thing. This is also called a three phase fault, since all three phases are involved.
What are the types of faults in ehv transmission lines?
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
What are the limitations of gauss law?
gauss law is applicable to certain symmetrical shapes it cannot be used for disk and ring
What is magnetic balance test of transformer?
The Magnetic Balance test is conducted on Transformers to identify inter turn faults and magnetic imbalance.
What are symmetrical faults?
A three-phase symmetrical fault exists when all three line conductors are short-circuited, sometimes to earth (ground). An unsymmetrical fault occurs when only one or two of the three lines are involved.
Difference between unsymmetrical and symmetrical bending?
unsymmetrical bending
What do you mean by unsymmetrical port timing diagram?
Timing s not symmetrical
Why does an unsymmetrical wing have more lift than an symmetrical wing at zero angle of attack?
Bernoulli's theorem
Why are symmetrical faults more severe than unsymmetrical faults?
In power engineering, specifically three-phase power, a symmetric, symmetrical or balanced fault is a fault which affects each of the three-phases equally.In power engineering, specifically three phase power, an asymmetricor unbalanced fault is a fault which does not affect each of the three phases equally.for these reasons thus symmetrical faults are more severe than the former.

What are unsymmetrical alkenes?
Unsymmetrical alkenes is molecule which is an pair of ligands. The molecule has doubly bonded carbon.
Having no symmetry is called what?
unsymmetrical
What is a symmetrical fault?
generally faults are of symmentrical and unsymmentrical faults that occur in majorly occurs in transmission lines........ the fault in electrical transmission line which give rise to symmetrical fault current is called symmetric fault. e.g; L-L-L-G fault. if they are in low values then system is said to be "protected" .... In order to avoid those NEUTRAL SHOULD GROUND with resistor or reactor etc,,,,,,,,...........
A molecule in which the polar covalent bonds do not cancel out?
unsymmetrical
Another word for not the same on both sides?
unsymmetrical asymmetrical
What is unsymmetrical current?
it means those currents those are short circuit.
Is a arrow symmetrical?
is a arrow symmetrical
