1. Directional impedance relays (mho relays) are frequently used in high-voltage power systems.

2. In this paper, the operation margin of mho relays(zone 3 impedance relays) is equivalently redefined as function of bus voltages instead of line impedance.

3. Afterwards, had intelligent young people to call Iraq mho Holland too Pu, when gave Egypt the pharaoh to fill left the king designed the grave, has invented one new method of construction.

4. In this paper, a new mho relay based on adaptive principle is proposed.

5. Talking of mode of payment , can you advise mho of your regular practice In this respect?
