Setting calculations Time delay of power swing carrier send distance protection zones Time delay for the underreaching or overreaching carrier send power swing zone should be set shorter (with sufficient margin) than the time delay of normal distance protection zone 2 to obtain selective time grading also in cases of faults during power swings.

The necessary time difference depends mostly on the speed of the communication channel used, speed of the circuit breaker used, etc.

Time difference between 100 ms and 150 ms is generally sufficient. Reactive reach setting of power swing distance protection zones Set the reactive reach for the power swing zones according to the system selectivity planning. The reach of the underreaching zone should not exceed 85% of the protected line length.

The reach of the overreaching zone should be at least 120% of the protected line length.
