Distance Elements for Line Protection Applications Near

To limit their potential for misoperation, distance elements may be inhibited when the protection channel is available, and the relay logic may engage distance elements only when the protection channel fails.

Protective relay

Distance relays, also known as impedance relay, differ in principle from other forms of protection in that their performance is not governed by the magnitude of the
