7) documentation of the inspection and maintenance of:
a) the electrical plant
b) tools, equipment and devices;
8) internal audit reports, a copy of the internal evaluation of the quality management system for operation and the Danish Safety Technology Authority's inspection reports.

Appendix 2: The distances DL and DV

The distance DL (danger zone)
This distance indicates the outer boundary of the danger zone.
The distance depends on the operating voltage and is calculated in air from any insufficiently insulated part under voltage of the electrical plant.
The size of the distance DL at the various operating voltages is shown in the table in Figure 1.

At voltages other than those given in the table, DL can be determined by linear interpolation.
The distances DV (proximity zone)
This distance indicates the outer boundary of the proximity zone.
The distance depends on the operating voltage and is calculated in air from any insufficiently insulated part under voltage of the electrical plant.
The area between the distance DV and the distance DL from a part under voltage of a plant is known as the proximity zone.
Figure 1 Table of DL and DV distances.

EL Distance DL and DV 10102018

Since there are no calculation methods for DC systems, the values for the DL and DV distance for AC systems are also used for DC systems below 500 kV.
At low voltage, DV is set to 500 mm. At high voltage, DV is set to DL + 1000 mm if the rated operating voltage does not exceed 60 kV, and to DL + 2000 mm if the rated operating voltage exceeds 60 kV, see the table in Figure 1.
