Open Circuit Test


Objective: To obtain the magnetization characteristic and therefore determine the critical field resistance and critical speed of the given dc shunt generator.



Preview: The EMF induced in a DC machine is proportional to the flux per pole, the number of conductors and speed. This EMF depends on speed and flux. As the flux increases the EMF increases beyond a point the flux gets saturated. The BH curve of the core depicts the magnetization curve of the machine.

(A) Critical Speed of a DC Shunt Generator


Objective: To determine the critical speed of a dc shunt generator. With the fixed excitation and variable speed, as the speed reduces the OCC proportionally slides down so that the no load voltage reduces. At a particular speed, called the critical speed, the OCC is tangential to the Rf line and as a result the generator fails to excite.
