Section 3

HANDLING THE AIR LINE INCIDENT WITHOUT VOLTAGE FROM 35 KV BACK DOWN

What? 23. The handling of the operator when the upper-line incident does not grant electricity from 35 kV back down

When the wire cutter, the operator operator at the power plant, the power station, the control center or the distribution grid has a fixed line-up line that is immediately reported to the Level Level that controls the following information:

1. The name of the cutter, the number of jumps, the status of the cutting machine.

2. Rous for automatic automatic protection, the signals have instructed, the record number of incidents recorded in the tile or other specialized devices.

3. Wireless voltage status.

4. The work status of the other devices is relevant.

5. local weather.

What? 24. The handling of the Condition when the upper-line incident does not level voltage from 35 kV back down

1. The auto-closed case closed successfully, which must gather information from the incident-terminal power stations, check the status of the cutter, the protective and automatic equipment, the line-up identified with the transient incident to the Transport Management Unit. Eye-checking with wire note bearing power, the point of suspicion of incident and completion of the incident report by the operation process and handling of the electrical system incident provided by the Level of Control that has the authority to control the issue.

2. The auto-closed case is not successful, having to take the necessary measures to prevent further expansion (overloading of line or equipment), quick analysis of the incident to restore the fixed line of the incident in accordance with regulations at Article 25 of this and complete. The incident report follows the operation of the operation and handles the electrical system incident due to the level of the administration's control over the issue.

3. The case shows the ground touch on the grid with a neutral point not connecting the land or connecting the soil through the arc of the arc, which must proceed immediately to the measures necessary to isolate the ground touch and implement some basic measures to identify and isolate the point. touch the ground to the grid with a neutral point or connecting the ground through the specific arc roll as follows:

a) Based on the record parameters received by the occurrence of the incident to determine the element of the incident, proceed to the segment, isolate the ground to the processing;

b) The case is not identified as the element of the incident, which must take steps in the following order:

-Check out the female elements and from the bar to the power station fence;

-The split grid has ground points to the areas for inspection;

-The operation to separate individual elements in the region with a soil touch point in the principle of separation of the element is less important until the detection of the element is found.

-After you locate the damaged element, you must proceed and isolate the ground to the ground.

4. In case of an undelayed emergency (the fire where the line passes or the device insufficiently standard operating is at risk of threatening the human life and the safety of the device; or flood that leads to a higher water level than the design water level) The line threatens to lose safety and other information issued by the Operations Management Unit, commander of the process line-cutting operation and is responsible for the manipulation of his incident.
