Arc Flash Forum • View topic – BGI/GUV-I arc flash calculation method

The first test, known as Class 1, uses a 4, Amp short circuit bbi at Volts to develop the arc from the box. Imprint About us Publisher: Determination of system electric arc energy in the event of a fault. Page 1 of 1. Do anyone knows about a arc flash calculation software that bvi DGUV method? Especially for the working area of public electric energy supply, as well as for widespread industry grids is this fact associated with a considerable extra effort at the hazard assessment.

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. Mon Oct 26, 1: You cannot post new topics in this forum You cannot bgii to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot post attachments in this forum.

bi Parameters and risk analysis of thermal hazards to persons related to electric arcing. The IEEE Standard is an internationally recognized standard and is used as the basis for most major software company’s arc flash programs.

Class 1 or Class 2 to use. 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.

Arc-Flash Analysis

Standards for protective clothing outside the EU. The most serious personal risks are bi with the thermal effects of electric fault arcs. The wide use of electrical energy in all areas of life leads to higher requirements on the safety and reliability of power supply systems. Fri Oct 23, 4: Thank you Jim for such complete answer. The following software features are worth to mention beyond: The specific method is more complex, therefore certain saftey additions can be reduced.

Procedures for selecting PPEgS. Since these installations and networks frequently cannot be disconnected for technical big organisational reasons, work must be performed under live conditions. Sun Nov 01, 3: The calculation method was big by a group of well regarded industry experts from Germany. Instructions for practical application with practical examples. No registered users and 0 guests. I wonder how engeneers perfom calculation in Europe using IEC if there insn’t software to solve it.

High intensity electromagnetic radiation, particularly in the ultraviolet UV and infrared IR radiation bands, but also in the visible light band, which can lead to irreversible damage to the eyes and skin. The second test is known bgk Class 2 and uses a 7, Amp current at Volts. A dialogue orientated menu guidance and a data bank supports a preselection for 518 parameters and installation requirements e.

This work may include live cleaning or refilling cable ends, but also disconnection, protection against re-connection and verifying that the installation is dead.

Design German Social Accident Insurance e. In so doing, a methodology has been bggi based on standardised Box test procedures according to VDE see Annex 1. You can also choose between a simplified and a precise calculation method.

The simplified method allows a small amount of specific installation knowledge, works therefore with higher safety additions. The result of your calculation will be shown as a integral component of a hazard assessment. Toxic gases and particles produced by melting and vaporised materials in the vicinity of the arc flash including electrodes. If the material or assembly passes the first arc test, it bgo classified as “Class 1” If it passes the second test, it is classified as Class 2.

Because doing manually or using excel spreadsheet is very dificult and not recommended for complex electrical networks. Besides the arc energy, the required test level of the PPE against electric arc will be shown as:.

This guideline describes that persons working on or in the vicinity of live parts of electrical installations are generally exposed to the risk of arc faults — for example caused by short-circuits bti maloperation. BSD Arc Flash Software 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 construction form and the working distance necessary.

One problem with the classification method was how to determine which Class is necessary for suitable protection of the electrical worker. Examples bhi work locations for determining transmission factor k T. For this purpose, tested high-quality products are indispensable.

To this end, maintenance and repair work must be performed in electrical installations and networks.

DGUV Information 203-078 – Thermal hazards from electric fault arc Guide to the …

To prevent accidents, tested high-quality safety equipment products are indispensable. Persons working on or in the vicinity of live electrical equipment are, in principle, exposed to hazards associated with electric fault arc. That means, that a working place related hazard assessment has to be made.
