When a transformer winding suffers a short circuit the adjoining turns of the same winding experiences?
A short circuit between adjacent turns of the same winding will cause the turns ratio of the transformer to change. A short circuit of this nature may not cause the transformer to become disconnected, so the situation could last for a long time. In larger utility transformers, the gases formed by the arcing between turns will collect in the Buchholz relay, situated between the transformer and its expansion tank, which will then initiate an alarm inside the substation.
What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
What will happen when field winding of dc shunt motor is disconnected?
Typical applications; "the motor will have a limited amount of torque, lesser in value than what is needed for normal operation. Thus, is real world workings the unit will overload, stop, not work, trip OL.
What is a y configuration on a 3 phase circuit?
On a wye connection all three ends of the phase winding coils are connected together and grounded. The other end of the three phase winding are connected to the supply voltage.
Why you do insulation resistance test?
in order to avoid unwanted short circuit break downs.... short circuit can burn the transformer and motor winding.... Megger is the device used to check the insulation .
What is a high voltage circuit primary circuit secondary circuit tertiary circuit?
The terms 'primary', 'secondary', and 'tertiary' winding has absolutely nothing whatsoever to do with voltage levels. The primary winding is simply that winding connected to the supply, while the secondary winding is that winding connected to the load. The voltages of these windings depend on whether you are dealing with a step-up or step-down transformer.
When an open motor gets up to speed what switch takes to start winding out of the circuit?
Usually a centrifugal switch. When the rotor reaches proper speed, the weights fly out and move a set of contacts so they are disconnected, thereby disconnecting the starting circuit.

What is a Winding-To-Ground Short Circuit?
No
What is percent impedance?
The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage.It is also the percentage of the normal terminal voltage required to circulate full-load current under short circuit conditionsThe impedance is measured by means of a short circuit test. With one winding shorted, a voltage at the rated frequency is applied to the other winding sufficient to circulate full load currentZ% = Impedance Voltage x 100Rated Voltage

What is the base voltage in a transformer circuit?
depends on the type of trans former.buck or boost.primary winding a secondary winding
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
When a transformer winding suffers a short circuit the adjoining turns of the same winding experiences what force?
Both radial and axial forces.
What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
WHAT STOPS a transformer windings FROM BEING A short circuit?
The transformer winding is a short circuit to DC. But for AC, the impedance of thecoiled winding and the magnetic coupling to another winding have the same effecton AC as resistance has in a DC circuit. That's why transformers don't work withDC, and are always operated with AC.AnswerIf you are querying why there are no short circuits between individual turns, it is because the windings are insulated not bare.
What is the function for primary winding of transformer?
To limit the current flowing through the primary circuit.
