What is meant by swin burn test in dc shunt generator?
in swin burn test we find out the copar loses & iron loses of the dc generator
Where can you find a diagram for load test of a DC shunt motor?
See the diagram linked below.
What is theory of brake test on dc shunt motor?
Brake test is used to determine the efficiency of comparatively small motors. The motor is loaded directly by means of a mechanical brake (load) or by means of an eddy current or a calibrated air fan.
Can you test the output amps of a DC generator with no load?
Any voltage source, whether a generator or a battery, will NOT supply an output current unless it is connected to a load. So the only way to test the output current is by connecting it to a load.
What is needed to perform a no-load bench test?
A bench and no load! Whatever you are testing has no load. It might be a generator or a motor for example. If a motor it wouldn't be connected to anything. If a generator it would have nothing plugged in.

Is swinburnes test direct or indirect test?
in this test their is a no load on dc shunt motor so it is an indirect test
What is swinburne's test of DC shunt motor?
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
What about the load test on dc series generator?

When using a resistive load bank to test a generator do you load it to the kW or the kVA?
When using a resistive load bank to test a generator, it does not matter if you load the generator to its kW or kVA rating, because those two numbers are the same when considering a resistive load. Power factor, which is the difference between true and apparent power, only comes into play when there is a reactive (inductive or capacitative) load.

When using an external resistive load bank to test an engine driven generator do you load it to kVA or KW?
It does not matter, when testing a generator with a resistive load bank, if you load it to kVA or KW. For a resitive load, i.e. non-reactive load, the power factor is one, so kVA and kW are the same.
What is the theory for load test on dc compound generator?
Connect the circuit as per the circuit diagram shown in fig1. Keep the field regulator of the motor in the minimum resistance position and regulator of the generator in the maximum resistance position.2. Switch on the supply and start the motor with the help of its starter.3. Adjust the field regulator of the motor such that it runs its rated speed given on thename plate.4. Adjust the armature regulator of the generator to build up its rated voltage given on itsname plates on no load.5. Note down the no loads of ammeter and volt meter in tabular form.6. Increase the load gradually in steps and tabulate the readings7. Plot the external characteristics is load current Vs terminal voltage.8 Connect the generator for differentially compounding, repeat the process and plot theexternal characteristics.
