An open-delta three-phase transformer system has one transformer center-tapped to provide a neutral for single-phase voltages. I

f the voltage from line to center tap is 277 V, what is the high-leg voltage?

Answer:

 The  high-leg voltage is V_h= 497.76V

Explanation:

A diagram showing the arrangement of this three phase transformer is shown on the first uploaded image

The high - leg terminal is in the diagram is from Z_1 - n

Generally the high-leg terminal is 1.732 times of the the voltage from line to center tap which is given as 277 V

    The high -voltage can be computed as follows  

          V_h = 1.732 *277

               V_h= 497.76V

What two quantities must stay the same in order for an object to have a constant velocity?
pentagon [3]
<span>Velocity is a vector and it has both speed and direction. It takes a force to change direction just as it does to change speed</span>. In order to have a constant velocity the object must maintain a constant direction and speed. Hope this answers the questions. Have a nice day.

A damped mass/spring system takes 14.0 s for its amplitude of the oscillator to decrease by a factor of 9. By what factor does t
fiasKO [112]

Answer:

The correct answer is "0.246".

Explanation:

Given that the amplitude is decreased by a factor of 9, then

A \rightarrow (A-\frac{A}{9} )

A \rightarrow \frac{8A}{9}

As we know,

Energy will be:

⇒  E_{1}=\frac{1}{2}KA^2

and,

⇒  E_{2}=\frac{1}{2}K(\frac{8A}{9} )^2

          =\frac{64KA^2}{162}

⇒  \Delta E=E_1-E_2

On putting the estimated values, we get

           =\frac{1}{2}KA^2-\frac{64KA^2}{162}

⇒  \frac{\Delta E}{E}=\frac{\frac{20}{162}KA^2}{\frac{1}{2}KA^2}

          =\frac{40}{162}

          =0.246
