What are the ways you use to reduce the tripping time?
Where can I get rid of the coordination interval between two relays to reduce the total tripping time?
 
Faster breakers? More accurate CT's, PT's, and relays?
Sort of depends on the conditions you are asking about.
 
Not really any way to "get rid" of coordination time, unless you want to add a ZSI scheme or something similar. Even then you have to account for communication delays.

Is this for transmission, distribution, or industrial?
It is for industrial and distribution.
 
There might be quite a lot of things than can be done, depending on what equipment currently exists and how much you are able to spend. Your system needs to be properly studied and designed though.
