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:

  1. Impedance relays
  2. Reactance relays
  3. MHO relays
  4. Angle impedance relays
  5. Quadrilateral relays
  6. Elliptical and other conic section relays
