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.
What else can I help you with?
Short Circuit test of a Synchronous Generator?
synchronous generator
What is Doubling Effect in power system?
It is define as twice the maximum symetrical short circuit current.
Why alternator is much less likely to burn out on a sustained short circuit than a separately excited dc shunt generator?
Because the Power Factor is over corrected.
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
Short circuit example?
An example of a kind of short circuit is an arc welding.
How do you calculate short circuit capacity of generator by using reactance of the winding?
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.
What is the design value of short circuit ration of generator?
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.
Incase of short circuit will the generator start or not?
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
Short Circuit test of a Synchronous Generator?
synchronous generator
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
Is there any effect on fault level if generator short circuit ratio is high or low?
Probably... What ratio? X/R? X0/X1? X0/R0? Xd /Xd''? etc.
Is it possible to load a shunt generator to short circuit and not injure the machine?
A
How does good regulation affect the short-circuit current of an ac 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.
How can a tone generator be used to locate a short circuit?
Yes you can use both. They are also acutally the easiest way to find a short in an automotive circuit.
What is short circuit ratio?
Oh, dude, the short circuit ratio is basically the ratio of the maximum short circuit current to the rated current of a system. It's like when your phone battery is at 1% and you try to charge it with a potato - not gonna work out so well. So, yeah, it's just a fancy way of saying how much juice your system can handle in a pinch.
Short note on parity generator and checker?
devices and simulate the circuit using the VHDL codes.
What is Doubling Effect in power system?
It is define as twice the maximum symetrical short circuit current.
