The circuit diagram of a DC shunt wound generator is shown in the above fig. In that the armature current Ia ruptures up into 2 parts; a little fraction shunt current Ish flowing through shunt coil whereas the main part IL goes to the external load.
Open Circuit Characteristic
The fig shows that the open circuit characteristic of a DC shunt generator, which is similar in form to it of a series generator. The line OP signifies the shunt field circuit resistance. Once the generator is run at typical speed, it'll build up a voltage OM. At no-load, the terminal voltage of the generator are going to be constant (= OM) diagrammatical by the horizontal line MR.
The internal characteristic of a shunt Generator is shown in the curve 1. As soon as the generator gets loaded, flux per pole is decreased because of armature reaction. For that reason, e.m.f. E generated on load is a smaller amount than the e.m.f. generated at no load. Thus the internal characteristics curve of shunt generator (E/Ia) drops down slightly as shown in Fig.
The external characteristic of a shunt generator is shown in curve 2. This curve shows the relation between the terminal voltage V and load current IL.
= E-(IL+Ish) Ra
Hence, the external characteristic curve can lie under the internal characteristic curve by an equal amount up to the drop in the armature circuit [i.e., (IL + Ish) Ra].
Positive site, where did u come up with the information on this posting?I have read a few of the articles on your website now, and I really like your style. Thanks a million and please keep up the effective work. KRM Light+ReplyDelete
Consumers should, however, be aware of the dangers associated with improper use of electric generators. We will highlight a few of these in the following paragraphs.generatorguides.netReplyDelete
Thanks for sharing this quality information with us. I really enjoyed reading. Will surely going to share this URL with my friends. generator sri lankaReplyDelete
This can help tech support a ton in the event that they can get the model number of the PC, printer, and so forth you are attempting to get tech support for. Indeed, on the off chance that you incorporate this they may not have to request the details of the PC. IT consulting services BramptonReplyDelete
