Type KST Out-of-Step Tripping Relay
The KST relay takes advantage of the distinction between a fault and an out-of-step condition. Under out-of-step conditions, the KST relay will operate the OS telephone-type relay.
KS out-of-step blocking relay
The KST relay is used with another distance relay such as a KD-3 relay or the three-phase unit of a KD-4, KD-10, or a KD-11 to sense an out-of-step condition on a power system and to initiate tripping.
