Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
Why should current transformers be shunted before opening the secondary winding?
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.
How Impedance inversion may be obtained?

Why should the secondary of a voltage transformer not be 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.
What is Doubling Effect in power system?
It is define as twice the maximum symetrical short circuit current.
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
What happens if a dependent current source is short circuited?
Nothing happens.
What is Minimum diode Bypass current?
It depends of your panel ratings. usualy, a panel short-circuited has a maximum current, you can base the value on that. But if you are doing an array of panels, you have to pai attention to the parallel connection, once that multiplies the current across the circuit. in this case you have to use diodes that support the current of the array.
What precaution should be taken when working with current transformer that is in service?
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.
Why insulation is needed on current carrying conductors?
To prevent the wire from getting short circuited to ground or even to other wires.
How do you get an iPhone that has short circuited?
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.
Why the CT secondary short circuited?
Current transformers produce a ratio of primary current in the secondary. If the secondary of a CT is open circuited, and primary current is flowing, the CT will try to push that same ratio of current through the secondary open circuit. This causes secondary voltage to climb until it the secondary open circuit flashes over. This can often damage the CT.

When inductor is called short circuit and open circuit?
In DC inductor is short circuited .

When the current will be short and open circuited?
Open circuit has no current, so does that mean any resistor in series with it, has no current ,so it can be ignored for analysis( v=ir so 0 current means 0 V) for finding lets say the Thevenin equivalent.? Now for Short circuit, do we ignore a resistor in series with the short, because current will take path of least resistance and ignore that resistor? Also can short circuit have voltage through it ?
High level short circuit?
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.
