The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
Its secondary must never be open circuited. If its burden is to be removed, then the secondary must be short circuited first, and removed only after the burden is replaced.
An 'inter-turn' fault occurs when adjacent turns of the same winding are short circuited (due, for example, to insulation breakdown). This affects the turns ratio of the transformer. An 'inter-winding' fault occurs when there is a short circuit between adjacent windings (coils) due to insulation breakdown, and can lead to a catastrophic failure of the transformer.
The main board may be short-circuited
Nothing happens.

Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.

when its is short circuited there will not be any drop and hence the current will b maximum when its is short circuited there will not be any drop and hence the current will b maximum
Go to an ATT store, buy an iPhone, take it home and power it on. Then drop it in the toilet. There you go. iPhone that is short circuited.
A voltage transformer takes a primary voltage and steps it down to a smaller secondary voltage. This type of transformer will attempt to keep the secondary voltage at a specific ratio of the primary voltage. If you short it, massive current flow in the secondary is required to do this. For a similar reason a CT should never be open circuited - because it attempts to push a specific ratio of primary current through the secondary. If you open circuit the secondary, it takes a massive voltage on the secondary to accomplish this.
A current transformer's secondary must never be open-circuited. If the instrument fed by a CT needs to be removed, then the secondary terminals must be short-circuited first. This is because a large, and potentially-dangerous, secondary voltage will appear across an open-circuited CT. Normally, a set of links is provided at those terminals for this purpose.
In DC inductor is short circuited .
short circuited stub
The short circuited path is the one which doesn't have any distributed elements(i.e., resistors, inductors,etc...). So the highly short circuited means only 'the connecting wire' is present in the circuit.
A short-circuit test is done to determine the power lost in the resistance of the primary and secondary windings of the transformer. It is done at full load current but with only enough voltage to give the required current with the secondary short circuited. An open-circuit test is done at full load voltage but no current is taken from the secondary, and this enables the power lost in the magnetic core of the transformer to be measured. As well a power, the tests also allow the inductances to be measured as well as the resistances, in order ot characterise the transformer fully.
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
