What is the symbol that indicates two triangles are similar?
Three parallel vertical lines. A bit like triangle ABC | triangle DEF, except that the lines are closer together.
The distance between two contour lines indicates?
the steepness of an area
What type of transformer is best suited in generating end Dy11 or Dy1 and Why?
The difference between a Dy11 (delta winding lags the wye winding by 30 degrees) and a Dy1 (delta winding leads the wye winding by 30 degrees) is a phase shift. One is not better than another in a general sence. Depending on the configuration of the plant and surrounding power lines and transformers, one may be more beneficial than the other by allowing the plant to sync to the grid through multiple sources without first disconnecting.
What does the lines between primary and secondary coils of transformer signify?
The voltage in a transformer is transferred from primary coil to secondary coil through electromagnetic induction. There is no physical connectivity between these two. instead they are linked by an alternating magnetic field created in the soft-iron core of the transformer.The two lines in the middle of the circuit symbol represent the core of the transformer.

Under what condition is a transformer connected in star?
Depends on the design criteria. A grounded star transformer winding will provide zero sequence (ground) current, so it can be used for polarizing of protective relays. The extra ground current may be a requirement of the system to guarantee protective device operation.The three phase windings in a generator / transformer / motor can be interconnected in two ways:STARIf the similar ends of the coils are connected together and the other ends are connected to the 3 incoming supply service lines, that is called "star connection". The internally-connected point is brought out as the "neutral" connection. The service "line-to-line" voltage (between any 2 lines) is 1.732 times the voltage between any line and neutral. Thus we can get two voltages for distribution within a building or site to supply lighting and power. However the service line currents are the same as the phase winding currents.DELTAIf the dissimilar ends of each winding are labelled A and B and the three windings are then connected together B->A, B->A, B->A, and the 3 incomiing supply service lines are then connected to the junctions, it is called DELTA. Here the values of line voltage and phase voltage are the same while the service line currents are 1.732 times the phase winding currents.Additional AnswerIn Britain, the secondary windings of a three-phase distribution transformer are always star- (wye-) connected, with the star (neutral) point earthed. This provides a three-phase distribution system, with 400 V between lines, and 230 V between line and neutral. Residences are connected line-to-neutral, providing 230-V single-phase service; premises that require three-phase supplies are provided with three lines and a neutral.
What is meant by star connection for a transformer?
The three phase windings in a transformer / generator / motor can be interconnected in two ways:STARIf the similar ends of each winding are connected together and the other ends are connected to the 3 incoming supply service lines, that is called "star connection". The centrally-connected point is known as the "neutral" connection point. The service "line-to-line" voltage (between any 2 lines) is 1.732 times the voltage between any line and neutral. Thus we can get two voltages for distribution within a building or site to supply lighting and power. However the service line currents are the same as the phase winding currents.DELTAIf the dissimilar ends of each winding are labelled A and B and the three windings are then connected together B->A, B->A, B->A, and the 3 incomiing supply service lines are then connected to the junctions, that is called "delta connection". Here the values of line voltage and phase voltage are the same while the service line currents are 1.732 times the phase winding currents.For more information see the answers to the Related Questions shown below.
What does a transformer between utility wires and your house do?
The transformer steps down the voltage from 600kilo volts which is what is at the power pole/lines to multiple strands of 120v or hot wires which is what your house runs off of.
What do rapid increases mean on a topographic map?
This indicates steeply ascending or descending terrain. The distance between the lines indicates different elevations, so lines that are closer together indicate steep places while lines that are farther apart indicate smoother terrain.
What is step up tranformer?
A step-up transformer is a transformer that increases voltage that is transferred through power lines.
What indicates elevation on a topographic map?
Brown lines
How does the flux generated in the primary winding get linked to the secondary winding in an ideal transformer?
The iron core of the transformer concentrates the magnetic lines of force from the primary winding through the iron core. The secondary coil winding is also wound on the same iron core so the primary flux cuts the secondary winding inducing a current into that coil.Alternative AnswerWhat you have to understand is that lines of magnetic flux don't actually exist! They simply represent a 'model', created by Michael Faraday, as a means of providing a visual representation of a magnetic field, and the behaviour of these lines simply follow rules defined by Faraday as part of his model! Many teachers fail to explain the difference between a 'model', such as this one, and 'reality'. Many students are then left not understanding that what they have learnt is simply a model, and that the actual behaviour of a circuit is far more complicated and, in many circumstances, cannot be adequately explained at all!So, while Faraday's model works well to explain the behaviour of a magnetic field in some circumstances(e.g. motor and generator action), it does not in others.For example, this model completely fails when it comes to explaining the behaviour of a transformer because, if these lines of force are confined within the transformer's core, they clearly cannot 'cut' the secondary windings -as often described in many textbooks- because they merely pass through the centre of the secondary coil without 'cutting' the coiled conductors!For this reason, when we explain the behaviour of a transformer, we describe the magnetic flux as 'linking', rather than 'cutting' the secondary winding. But there is no explanation of whyflux that 'links' a coil should induce a voltage into that coil. Faraday's 'flux lines' model simply doesn't explain what is going on and, in fact, there is no simple explanation!! You could say, 'it simply happens' and leave it there!There are lots of other models used in electrical engineering, which students, unfortunately seem to accept as reality! For example, Bohr's model of the atom, used as the basis of the 'electron theory' to describe electric current, bears no relationship whatsoever to a real atom because the structure of real atoms is probably beyond most people's understanding.
