Want this question answered?
Through a relay or some other kind of high voltage switching device.
In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
Because a short-circuit test is done at very low voltage to check the transformer windings on their maximum current. The low voltage ensures that the magnetic flux in the transformer's iron core is very low so that the eddy-current losses, usually known as iron losses, are negligible.
One does NOT insert a voltmeter in a series cirtcuit...an ammeter can be inserted in series, though. A voltmeter is connected in parallel with the source voltage and low(ground) side.
transformer is busted; if input voltage is normal you have short circuit or open circuit somewhere
That depends on what you mean. If you mean why does a circuit which has a high voltage side and a low voltage side have a greater average current on the low voltage side, it is probably because of power conservation: P = IV. If this is not what you mean, you will have to be more specific!

Its By Switching Off The Circuit
chroma circuit, luminance circuit, picture tube, vertical and horizontal circuits, sync circuit, high voltage circuit, low voltage power supply
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.

Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
