Define generator short circuit ratio?
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.
Short Circuit test of a Synchronous Generator?
synchronous generator
What are the characteristics of dc shunt generator?
The open-circuit characheristics and the load characheristics
What device can provide the energy for an electric circuit?
A battery, generator, or solar cell can.
In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
What is a generator breaker?
The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
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

How many amperes will a 28-volt generator be required to supply to a circuit containing five lamps?
It depends on how much power the lamps require, and on how they are connected.
Which part of the circuit supplies the potential difference in the circuit?
A battery or a generator.
What is a brush less generator?
It is self excited generator, no external excitation circuit.
What A battery or generator?
It provides energy for a circuit.
Is both circuit breaker and circuit gear have same functions?
circuit breaker is break the electrical circuit .circuit gear is generator analyzer
A battery or generator provides what?
It provides energy for a circuit.
How do you calculate short circuit capacity of generator by using reactance of the winding?
(Generator kVA / Subtransient Reactance % ) / (1.73 x Voltage) = Short Circuit Current in kA
