During the usage of the DGUV Information (BGI ) to determine the necessary protection level of the PPE against electric arcs are the information. – Thermal hazards from electric fault arc Guide to the selection of personal protective equipment for electrical work (bisher: BGI/GUV-I E). *The representative selection does not replace a risk assessment according to BGI transformer output. (kVA) tripping time of the protective device (ms).

Especially for the working area of public electric energy supply, as well as for widespread industry bg is this fact associated with a considerable extra effort at the hazard assessment. Sun Nov 01, 3: More information in PDF format: If the material or assembly passes the first arc test, it is classified as “Class 1” If it passes the second test, it is classified as Class 2.
Do anyone knows about a arc flash calculation software that use DGUV method? Standards for protective clothing outside the EU. One problem with the 5818 method was how to determine which Class is necessary for suitable protection of the electrical worker.
Mon Oct 26, 1: Page 1 of 1. During the usage of the DGUV Information BGI to determine the necessary protection level of the PPE against electric arcs are the information about short-circuit current, grid voltage, arc burning time, installation bbi form and the working distance necessary.
Energy parameters for thermal hazards to persons related to electric arcing. This supports the calculation of the electric arc energy, if the necessary value for the short-circuit current does not exist. The simplified method allows a small amount of specific installation knowledge, works therefore with higher safety additions.

I wonder how engeneers perfom calculation in Europe using IEC if there insn’t software to solve it.
The wide use of electrical energy in all areas of life leads to higher requirements on the safety and reliability of power supply systems. You can also choose between a simplified and a precise calculation method. Class 1 or Class 2 to use.
Arc Flash Forum • View topic – BGI/GUV-I arc flash calculation method
German Social Accident Insurance e. Simply basing a Class on 4 kA and 7 kA did not provide a suitable 518 for application guidance.
To prevent interruption and failure of the energy supply, installations must be protected and maintenance and repair work must be performed. The second test is known as Class 2 and uses a 7, Amp current at Volts. Depending on the electrical network and equipment configuration, electric arcing can be extremely hazardous:. Toxic gases and particles produced by melting and vaporised materials in the vicinity of the arc flash including electrodes. Imprint About us Publisher: The result of your calculation will be shown as a integral component of a hazard assessment.
On the one hand for the precise method can be arc protection class 1 enough, on the other hand the simplified method can demand class 2 for the same working place.

Thank you Jim for such complete answer. To prevent accidents, tested high-quality safety equipment products are indispensable.
Examples of work locations for determining transmission factor k T. The information contained herein is intended to support employers in their selection of suitable equipment bgii. DGUV Information – Thermal hazards from electric fault arc Guide to the selection of personal protective equipment for electrical work bisher: There are no corresponding incident energy values measured during the “box test” and the Class system does not have any listed attribute that could be used for selecting a protection class.
A dialogue orientated menu guidance and a data bank supports a preselection for different parameters and installation requirements e. For this purpose, tested high-quality products are indispensable.
