Abstract |
|
This Synchro check relay can be used to assist in the semi-automatic paralleling of two ac power systems. It is the intention of this presentation to provide an explanation of the automatic synchronizing process, to explore the considerations involved and to look at some synchronizing applications for selection of the proper synchronizer. Synchronizing, in its simplest form, is the process of electrically connecting additional Generators to an existing bus. Paralleling protector provides Manual /automatic switching of generator to bus bar without damage or disturbance to the system. The volt - free relay contacts change state when the voltage level, phase relationship and frequency are within the selected synchronizing limits. Connecting two electrical systems that are not closely matched can cause expensive damage and disturbance to the electrical system. Using this relay will ensure that damage will not occur. |
