short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
Yes the generator engine will start and keep running. The generator has to start before the short circuit is sensed. What happens to the generator section on a short circuit condition is that the generator breaker will trip and disconnect the short circuit on the load. <<>> genarator will not start because of short circuit
The short circuit capacity of a generator can be calculated by dividing the generator's reactance by the sum of the generator's reactance and the total reactance of the system. This ratio will give you the short circuit capacity of the generator in relation to the total system capacity.
synchronous generator

I assume by good regulation you mean a minimal voltage drop internal to the generator. Minimizing this will inherently increase the short circuit current, because it requires minimizing the internal impedance of the generator.
Checked Stephen J. Chapman's Electric Machinery Fundamentals page 287. It says: Short Circuit Ratio (SCR) for the synchronous generator is the ratio of the field current required for the rated voltage at OPEN circuit to the field current require for the rated armature current at SHORT circuit.
Yes you can use both. They are also acutally the easiest way to find a short in an automotive circuit.
devices and simulate the circuit using the VHDL codes.
Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit.A short circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.
To provide the data necessary to design protection systems.
Hopefully the current and voltage would be zero. The generators overload and short circuit main breaker protection is there just for conditions like that. As soon as the fault is recognized by the protection the generator is taken off line.
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
