Can DC series generator start on no load?
yes.it is possible to start dc series generator on no load condition
Theory for load test on dc shunt generator?
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.
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.
Why should dc series motor can be operated for no load and light load?
dc motors can be operated at no load as well as at load condition.But by using the swin burns test the efficiency can be calculated at no load which is more benficial than load test.At industries this swin burns test is used because for load test we have to give separate supply for the load to run.In no load test that power is saved.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
Is Swinburne test applicable for dc series machine?
No.it is not applicable for dc series motor at no load..at no load armature current is too small in dc series motor and we know that speed is inversly proportional to the armature current(speed=v/kI-Ir/k).Hence speed is dangerously high which is not efficient for Swimburne's test...
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
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
What is a compound dc generator?
generators are machines that convert machanical energy to electrical energy and could be AC or DC. if in a DC generator has it field armature connection in both series and parallel its said to be compound dc generator.
Types of generators?
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound Generator
What are the characteristics of dc shunt generator?
The open-circuit characheristics and the load characheristics
What is the difference between a seperately excited DC generator and DC shunt generator?
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
