- For over compound generator, full load terminal voltage is higher than the no-load terminal voltage
- In the case of a flat or level compound generator, the terminal voltage at the full load is equal to the no-load terminal voltage
- In an under-compound generator, the terminal voltage at the full load is less than the no-load terminal voltage
- In Differential Compounded Generators, the terminal voltage drops very quickly with the increasing armature current
