Westinghouse CO Relay Curve

Westinghouse CO Relay Curve

Westinghouse CO Relay Curve

(OP)
Hi,
Can someone please tell me where I can download Westinghouse Relay CO time curve for CO7, CO8, CO9 and CO11 or any equations?

Thanks.

RE: Westinghouse CO Relay Curve

You might be able to find it in the Westinghouse or TECO (Tiwan(sp) Electric Co.) site as well.
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
