The lockout relay is a latching device that, besides mutplying contacts, is intended to make it difficult to reset. Our intent was always to make someone go to the substation, and look at things. The operator in the bunker could not restore what was locked out without sending someone to the substation.(86LO)
However, this is different from a reclose lockout, which only latches so that there can be no more recloses. The operator in the bunker can restore the circuit remotely. (79LO)
