When the distance exceeds 10 km, the short circuit current decreases to 1/5 or less of the current of the fault at point-blank range, from the OCR. Table 1 shows the short circuit current values for each end fault with the line length and load current (0 to 440 A) being parameters. The table indicates that the reach for LNS is 10 to 17 km, which is quite short.
