Control Systems

 * BIBO stable: largest pole inside unit circle.
 * Minimum phase: causal and stable (BIBO). TF has unique inverse. Inverse also will be minimum phase. Hence all poles and zeroes inside unit circle.

Relays

 * Non-directional over-current relays: at generator end
 * Directional over-current relays: at load end
