RE: Westinghouse CO Relay Curve
However I would suggest that you look in the Basler web site under protective relays (or call your local rep) and look at their solid state relay set up curves. I have found them (W) CO curves there.

On equations, there is IEEE C37.112-1996 Standard Inverse-Time Characteristic Equations for Overcurrent Relays Abstract
