Distance relays are generally
Right Answer is:
Mho relays
SOLUTION
A distance protection scheme is a non-unit system of protection. A single scheme provides both primary and backup protection.
The most important and versatile family of relays is the distance-relay group. It includes the following types:
- Impedance relays
- Reactance relays
- MHO relays
- Angle impedance relays
- Quadrilateral relays
- Elliptical and other conic section relays
