What is reverse blocking scheme in ht switchgears?

 

Responding to Paul's Sep 14, 12:21am query... if you are referring to protective relaying schemes, then I am familiar with two applications:

1) Carrier-based protective relaying of transmission lines fitted with zone protection.

2) Protective relaying associated with parallel or multi-ended lines.

If the above coincides with your information quest, please contact me!
