as distance relay is an impedance relay & measures impedance interms of current & voltage.
first zone : 85% of the selected ist portion's impedance interms of resistance & reactance. normally we use 85% to 90% of ist portion to avoid any human & other CT & PT's instruments errors.
secound zone: selected zone ist + 50% of the secound selected portions.
Third ZOne: selected zone ist + zone 2nd + 20% of the thrid selected portions.
Distance relay is CT & PT operated relay & give us exact location of the fault after measuring the level of the fault current & voltage.
