Hi, We have new ongoing project in our plant to upgrade the power by adding 2 frame5 generators to the network. Hence, the new generators are designed with 4 poles, 1500RPM. Whereby, the existing generators are designed with 2 poles , 3000 RPM. The frequency is maintained to 50Hz. Can someone explains the benefits of increasing the number poles from 2 to 4? Why the manufacturer didn't design like to like generator? Will that change have negative impact to our network?
