For this reason, persons working in this environment will require reliable protection, especially because incorrectly performed work tasks can cause such arcing.

The specific method is more complex, therefore certain saftey additions can be reduced. German Social Accident Insurance e.

The second test is known as Class 2 and uses a 7, Amp current at Volts. To prevent interruption and failure of the energy supply, installations must be protected and maintenance and repair work must be performed.

The first test, known as Class 1, uses a 4, Amp short circuit current at Volts to develop the arc from the box. Mon Oct 26, 1: DGUV Information – Thermal hazards from electric fault arc Guide to the selection of personal protective equipment for electrical work bisher: Mon Dec 31, 5: Determination of system electric arc energy in the event of a fault.

That means, that a working place related hazard assessment has to be made. This work may include live cleaning or refilling cable ends, but also disconnection, protection against re-connection and verifying that the installation is dead. A dialogue orientated menu guidance and a data bank supports a preselection for different parameters and installation requirements e.

Each consequence, in itself, can endanger the health and even the life of a person in proximity of the occurrence. While an electric arc flash is rare in the normal working environment, its occurrence cannot be ruled out completely. Besides the arc energy, the required test level of the PPE against electric arc will be shown as:.

Because doing manually or bgu excel spreadsheet is very dificult and not recommended for complex electrical networks. Since these installations and networks frequently cannot be disconnected for technical and organisational reasons, work must be performed under live conditions.

Electric arcs are not only induced by short circuiting, but can also occur between two current-carrying components, when they are separated from each other e. The Big Standard is an internationally recognized standard and is used as the basis for most major software company’s arc flash programs. The wide use of electrical energy in all areas of life leads to higher requirements on the safety and reliability of 1588 supply systems. 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.

Class 1 or Class 2 to use. The vgi serious personal risks are associated with the thermal effects of electric fault arcs. Standardisation of PPE against the thermal effects of electric fault arcing.

Specification standards for product approval and selection. You can also choose between a simplified and a precise calculation method.

Design German Social Accident Insurance e. 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 or maloperation.

Moreover, an overview of PPE selection is included in the ISSA International Social Security Association Guideline for the selection of personal protective equipment when exposed to the thermal effects of an electric fault arc 2nd edition Thank you Jim for bgii complete answer.
