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.
What Generator has shunt windings and series windings?
A 'compund wound' dc generator has shunt winding and a series winding. The shunt winding has a high resistance, and draws only a small current from the armature, but as it has many turns of wire on it, it generates a strong magnetic field. The series winding has only a few turns of wire on it, and, even though it has a large current in it, its magnetic field is usually less than that of the shunt field. Because of this, the compound generator behaves in most ways like a shunt generator, and is controlled in the same way. As it is self-excited, the compound wound generator requires 'residual flux' to start the generating process. The series winding, if connected to AID the shunt field, can boost the field flux as load comes onto the machine and correct for the normal 'droop' in output voltage as the load increases. If set up properly, this correction makes the generator self-regulating. Because the fields aid each-other, this connection is called 'cumulative compounded'. This type of machine is the workhorse of the larger generator market. If the series field winding is connected so it's field OPPOSES the shunt field, then the output voltage of the generator collapses as the machine is loaded up. This connection is referred to as 'differential compounded', and is only used for arc welding generators - they have a high voltage before the arc is struck; a fairly low voltage during welding operations, and if the rod sticks to the work, they shut the generator down without damaging it.

Which is usually produced by a generator ac or DC?
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
What are the types of generations?
There are 2 major forms of generators. one is a synchronous generator that converts mechanical power to ac power. the other is a dc generator. there are 5 basic categories of a dc generator: 1)seperately excited generator 2)shunt generator 3)series generator 4)cumulatively compounded generator 5)differentially compounded generator

What are the application of differential compound generator?
Differential compounded generators are used in Ward Lenard motor generator loops. The shunt fields on these generators are separately excited and when the shunt field polarity is reversed by the controller the series field helps drive the generator voltage to zero thus aiding in the reversal of current.

What does a flat billed hat represent?
An individual who has an over-inflated sense of self worth, compounded by a low level ofintelligencebehaving ridiculously in front of colleagues with no sense of how moronic he appears.
