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
What else can I help you with?
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 do ground fault relays do?
Ground fault relays sense ground faults in the circuit and trigger a circuit breaker to trip off
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.
What do you mean by unsymmetrical port timing diagram?
Timing s not symmetrical
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.

Difference between unsymmetrical and symmetrical bending?
Symmetrical bending occurs when a beam is loaded uniformly along its length, resulting in bending stresses that are equal on both sides of the beam's neutral axis. Unsymmetrical bending occurs when a beam is loaded unevenly, causing different magnitudes of bending stress on opposite sides of the beam's neutral axis.
Why does an unsymmetrical wing have more lift than an symmetrical wing at zero angle of attack?
Bernoulli's theorem
How many possible isomers could exist for diacetylferrocene?
Diacetylferrocene can have three possible isomers: symmetrical cis-diacetylferrocene, symmetrical trans-diacetylferrocene, and unsymmetrical diacetylferrocene.
How to identify severe case of unsymmetrical fault?
A severe case of unsymmetrical fault can be identified by analyzing the voltage and current waveforms during the fault condition. Look for large imbalances in phase voltages and currents, significant distortion in the waveforms, and high fault currents. Additionally, monitoring any abnormal behavior in protective relays and equipment can also help in identifying severe unsymmetrical faults.
What is the difference of symmetrical and unsymmetrical?
Symmetrical refers to objects or shapes that are balanced and proportionate, having identical halves that mirror each other when divided along a central axis. In contrast, unsymmetrical refers to objects or shapes that lack this balance and proportion, exhibiting irregularities or differences on either side of a dividing line. Symmetry is often associated with harmony and aesthetics, while asymmetry can convey dynamism and interest in design and art.
What are unsymmetrical alkenes?
Unsymmetrical alkenes is molecule which is an pair of ligands. The molecule has doubly bonded carbon.
What is symmerical ketone?
A symmetrical ketone is a ketone where the two alkyl or aryl groups attached to the carbonyl carbon are identical. This means that the molecular structure on both sides of the carbonyl group is the same. Symmetrical ketones exhibit unique physical and chemical properties compared to unsymmetrical ketones.
Having no symmetry is called what?
unsymmetrical
How do you decide that molecule is symmetrical or unsym metrical?
A molecule is considered symmetrical if it exhibits symmetry elements such as planes of symmetry, centers of symmetry, or rotational symmetry. To determine this, one can analyze the molecular geometry and look for identical arrangements of atoms around a central point or axis. If the molecule can be divided into two mirror-image halves or rotated to match its original configuration without altering its appearance, it is symmetrical. Conversely, if no such symmetry can be found, the molecule is classified as unsymmetrical.
