What do you mean by unsymmetrical faults?

Unsymmetrical faults are normal fault which means the three phase lines become unbalanced (unequal currents with unequal phase shifts in a three phase system.) and they do not have the equal phase displacement each other’s. Coming to the types of faults, it occurs between line-to-ground or between lines.

What is symmetrical and unsymmetrical alkene?

The key difference between symmetrical and unsymmetrical alkenes is that symmetrical alkenes have doubly bonded carbon atoms bearing the same ligands, whereas unsymmetrical alkenes have doubly bonded carbon atoms bearing different ligands. Often, we call them olefins.

What is symmetrical and asymmetrical?

If you know that symmetrical means that both sides of something are identical, then it should be easy to learn that asymmetrical means the opposite: the two sides are different in some way. Asymmetrical things are irregular and crooked, and don’t match up perfectly when folded in half.

What are the types of symmetrical faults?

Two kinds of symmetrical faults include line to line to line (L-L-L) and line to line to line to ground (L-L-L-G) as shown in figure below. A rough occurrence of symmetrical faults is in the range of 2 to 5\% of the total system faults.

What is the unsymmetrical alkene?

An unsymmetrical alkene is an alkene in whose molecule the pair of ligands on one doubly bonded carbon is different from that on the other. In 1, one doubly bonded carbon bears two methyl groups and the other a methyl group and a hydrogen atom. Thus, 1 is an unsymmetrical alkene. eg.

What is symmetrical and unsymmetrical reagent?

Symmetrical reagents : are those reagents which are made up of same atoms. Unsymmetrical reagents : are those reagents which are made up of two different atoms. For example : H2O , HBr.

What is symmetry and example?

Symmetry is an attribute where something is the same on both sides of an axis. An example of symmetry is a circle that is the same on both sides if you fold it along its diameter.

What is the difference between symmetrical and unsymmetrical blading conditions of AFC?

Answer: Symmetrical faults are those faults which involve with all the three phase. it simply means that symmetrical faults affect all the three phases. On the other side, unsymmetrical faults are those faults in which either one or two phase involve. In unsymmetrical faults the three phase lines become unbalanced.

What is symmetrical and unsymmetrical fault in transmission line?

Symmetrical fault involves all the three phases, and these phases carry the identical fault current which makes the system balance. The unsymmetrical fault affects two or more phases of the transmission line.

What are symmetrical and unsymmetrical components?

Symmetrical components are derived to analyze unsymmetrical faults. The unsymmetrical network can be expressed in terms of three linear symmetrical components. The three symmetrical components are positive sequence component, negative sequence component and zero sequence component.

What is a balanced three phase unsymmetrical fault?

In balanced three-phase unsymmetrical faults, the fault occurs when all the three phases of the transmission line or the terminals of the machine come in contact with each other. Here let us consider an unloaded three-phase star-connected alternator.

What is the difference between unsymmetrical series and shunt faults?

An unsymmetrical series fault is between phases or between phase-to-ground, whereas unsymmetrical shunt fault is an unbalanced in the line impedances. Shunt fault in the three phase system can be classified as; Single line-to-ground fault (LG). Line-to-line fault (LL). Double Line-to-ground fault (LLG).
