Hydro Generators: braking systems
Hydro Generators: braking systems
(OP)
Hello everybody:
In some hydroelectric plants, AC generators have two braking systems: a pneumatic (used as principal) and an electrical braking (used as backup).
It is obvious the purpose of specifying an electrical braking system as backup but, what approach is followed in the power plants where is available only the traditional pneumatic braking system? This implies also ask what approach is followed in the power plants where both systems are specified?
The advantages and / or disadvantages of having one system or the two seem obvious, but it might not be.
I appreciate your comments.
By the way, Happy New Year!

Hi,
Sorry that I'm intruding into another topic. But you had started a topic on "Damage by Cavitation?" in 2008.
Because we are experiencing kind of similar damages on our diesel engines, I would like to ask if you have resolved the problem that you were experiencing
and what was or were the solution.
Thank in advance.
