Which relay is best suited for long distance protection?

A 132 kV transmission line has impedance of 50Ω. The line is protected by distance relay, and it is connected to the transmission line through a 132 kV/110V potential transformer and 1000/5A CT. The impedance seen by the relay for a fault at 80% of transmission line is
