	The size and use of the generator are some of the key factors for generator protection selection. As already indicated in the previous comments, the generator used for bicycle light usually is without protection. But the one used in nuclear or other power plant have plenty of protections. There are many documents available in the internet for your question. These are some of them. Read the documents from these links and you will get the answer in general. http://www.ee.siue.edu/~smuren/ECE%20545%20Notes/Ch%2011%20-%20Generator%20Protection.pdf http://www.gedigitalenergy.com/Multilin/notes/GET-8048A.pdf http://siemens.siprotec.de/download_neu/applications/Masch-Prot/Generator/7UM6_Gen_Prot-Schemes_E.pdf http://www.mantatest.com/GeneratorProtection.html - MS __________________ "All my technical advices in this forum must be consulted with and approved by a local registered professional engineer before implementation" - Mohammed Samad (Linkedin Profile: http://www.linkedin.com/in/msamad)

	A numerical relay is usually one size fit all. It is generally very detailed since the risks are much higher. __________________ Better not count the cent if the risk is many many dollars.
