a form of low voltage DC to high voltage AC power conversion circuit.
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.
generally open circuit test is performed on the low voltage side.....not on high voltage side.... becuase on low voltage side, we can apply that low voltage very easily ( i.e with a less amount of source is required)... whereas on high voltage side, we need a large power source in order to apply full voltage... in short circuit test, we will test on high voltage side by keeping Low voltage side being short circuit.because high voltage side needs less current source than low voltage side....
ARC VOLTAGE is the voltage that appears across the contacts of circuit breaker during the arcing period, during which the current flow is maintained in the form of an arc. The arc voltage value is low except for the point at which the current reaches zero when the arc voltage rises rapidly to a peak value.
When a voltage is present between two points in a circuit (electrical outlet, battery, etc.) it normally flows through a load of some resistance to do some work. If instead a pure conductor (usually metal) connects the two points separated by a voltage, a short circuit results. Current through the short circuit is very high and usually results in fire or failure unless protected by a circuit breaker. In low-voltage, low-power electronics a short circuit might not be dangerous but is usually undesirable.
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!

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.
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.

transformer is busted; if input voltage is normal you have short circuit or open circuit somewhere
