The company directly under the management of these generation and power supply units or branches and subsidiaries shall summarize the statistics as one accident.
6.2.2 In the event of a transient failure of a transmission line, which is caused by the failure of relay protection or substation equipment such as switches, it shall be classified as an accident of the unit which has jurisdiction over the substation equipment; in the event of a permanent failure of a transmission line, it shall be classified as an accident of the unit which has jurisdiction over the line, irrespective of whether or not the substation equipment is out of order.
6.2.3 If a line is maintained by two or more units, and the failure of the line to trip constitutes an accident, it shall be classified as an accident for each of the units if none of them finds the point of failure after inspection.
When a line is maintained by two or more units, and the line is tripped, if one side provides a fault recording map (or a fault rangefinder record, the same hereinafter), and the calculated point of failure is in the other side, and the other side fails to provide a fault recording map, and the two sides do not find the point of failure after on-site inspection, then it shall be classified as an accident for the side that did not record the wave.
If a party provides a fault recording map, the calculated point of failure in the side, the other side has recording equipment and failed to provide fault recording map, then each side is designated as an accident.
When the results calculated by analyzing the recording diagrams of both sides are contradictory, then each side is designated as an incident.
