What is the caused of unbalance of current during parallel running of two generator?

That depends on if the two machines are of equal KVA rating and also what type of Generator Control (Isochronous or Droop) each of the machines uses.

Is the induction motors running current or its locked rotor current more important in generator selection?
Running current. The locked rotor amps are only seen at initial start up which only lasts a fraction of a second to one or two seconds.
What causes generators in parallel with same voltages and KW to have different amps?
If they are at the same voltage, and the same kW, the only thing left that will influence the output amperage is the power factor the generator is running at.
Would a defective governor cause a generator motor not run?
Yes, if the governor failed in a way that "makes it think" the generator is always running too fast it might prevent the generator from running at all.
What will be happening when a generator is running but no output?
Many things are possible. Open circuit or winding. Blown fuse or circuit breaker. Loss of excitation current. Just to name three.
How can the power output of generators be coupled?
Generally speaking, the outputs of generators can be coupled by connecting the generators in parallel. In generators that produce DC (direct current), the voltages need to be equalized and the polarities of the connections needs to be observed. Both negatives are connected together and both positives connected together to create one parallel output. In an AC setup, the generators need to be running about the same voltage, and must be connected in phase for the setup to be successful. In practice, the generator that is being brought online is run up, and it frequency is allow to be a little bit faster than the unit that is online. When the phase difference is being observed, and the difference is approaching zero, at a "couple of degrees before" the zero, the generator that is being brought online is then connected to the grid and it "locks in" so that all the generators are running in phase. Connecting DC generators positive to negative is an invitation to disaster, and bringing an AC generator online 180 degrees out of phase with an running generator is the same kind of disaster. Shutting a breaker to parallel generators without insuring polarity concordance (in the case of the DC ones) or phase concordance (in the case of the AC ones) will pit one generator against the other, and severe damage will result.
What does Incoming and running generators are in same phase while paralleling two generators mean?
When two generators are to be run in parallel, one generator is first started and some load is given. Then second generator is brought in parallel with the running generator (subject few conditions, like voltage, frequency, phase angle). First generator which is running is known as running generator, the second generator which gets connected is known as incoming generator
Is there such thing as a sump pump connected to a generator?
Yes, a sump pump can be connected to a generator to make it operate. Keep in mind that the starting current of the pump motor could be 300% of the running current and the sizing of the generator should take this into account. If you are looking for the sump pump using a mechanical connection it will connect to the engine and not to the generator.

How much does it cost to run a diesel generator?
The cost of running a diesel generator can vary depending on various factors such as the size and efficiency of the generator, the price of diesel fuel, and the duration and frequency of usage. On average, diesel generators consume about 0.5 to 1 gallon of diesel fuel per hour for every kilowatt (kW) of power produced. To calculate the cost, you would need to know the current price of diesel fuel, the generator's fuel consumption rate, and the number of hours the generator will be running. By multiplying these factors together, you can determine the approximate cost of running a diesel generator.
Would a defective governor cause a generator motor not run?
Yes, if the governor failed in a way that "makes it think" the generator is always running too fast it might prevent the generator from running at all.
How is running water electricity?
Running water can turn a turbine that runs a generator.
How current passes through resistor.?
What is the current running through resistor four?1 amps..!What is the current running through resistor one? 3 amps...!What is the current running through resistor three? 2amps..!What is the current running through resistor five? 3 amps..!What is the voltage drop running through resistor five? 45 volts...!What is the equivalent resistance through the parallel portion of the circuit? 6 ohmsAnswerA resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.

What is the difference between and alternator and a generator?
Generator is the general term for mechanical devices that make electricity. Source: Webster's Revised Unabridged Dictionary (1913) Alternator is a type of generator. It is one of the most efficient, light and durable. Ideal for use in the automotive industry. A Generator (dynamo) produces DC direct current, An alternator produces Alternating curent whih is then converted into DC current with rectifiers/diodes as used in cars. When cars had generators (dynamos) in them you could test them by running a current into them and if they were ok the would turn like an electric motor.
