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).

In so doing, a methodology has been adopted based on standardised Box test procedures according to VDE see Annex 1. No registered users and 0 guests. 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 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 51888 2.
For this reason, persons working in this environment will require reliable protection, especially because incorrectly performed work tasks can cause such arcing.
I wonder how engeneers perfom calculation in Europe using IEC if there insn’t software to solve it. That means, that a working place related hazard assessment has to be made.
BSD – Arc flash software
Do anyone knows about a arc flash calculation software that use DGUV method? Especially for the working area of public electric energy supply, as well as for widespread industry grids is this fact associated hgi a considerable extra effort at the hazard assessment.
The simplified method allows a small amount of specific installation knowledge, works therefore with higher safety additions. The information contained herein is intended to support employers in their selection of suitable equipment e. Determination of system electric arc energy in bvi event of a fault.
Users browsing this forum: Page 1 of 1. Class 1 or Class 2 to use. Standardisation of PPE against the thermal effects of electric fault arcing.
The specific method is more complex, therefore certain saftey additions can be reduced. Depending on the electrical network and equipment configuration, electric arcing can be extremely hazardous:.
This work may include live cleaning or refilling cable ends, but also disconnection, protection against re-connection and verifying that the installation is dead. The most serious personal risks are associated with the thermal effects of electric fault arcs. Fri Oct 23, 4: DGUV Information – 55188 hazards from electric fault arc Guide to the selection of personal protective equipment for electrical work bisher: Size and expansion of the operated grid determined essential the amount of working places which has to be considered at a hazard assessment.
Bgu consequence, in itself, can endanger the health and even the life of a person in proximity of the occurrence. Examples of work locations for determining transmission factor k T. Full disclosure and disclaimer: There are no corresponding incident energy values measured during the “box test” and the Class bgu does not have any listed attribute that could be used for selecting a protection class.
PowerFactory – DIgSILENT
Simply basing a Class on 4 kA and 7 kA did not provide a suitable criteria for application guidance. Besides the arc energy, the required test level of the PPE against electric arc will be shown as:. The wide use of electrical energy in all areas of life leads to higher requirements on the safety and reliability of power supply systems. 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.
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. Bi About us Publisher: Parameters and risk analysis of thermal hazards to persons related to electric arcing.
To this end, maintenance and repair work must be performed in electrical installations and networks. Thermal hazards from electric fault arc Guide to the selection of personal protective equipment for electrical work bisher: Since these installations and networks frequently cannot be disconnected for technical and organisational reasons, work must be performed under live conditions.
The calculation method bggi developed by a group of well regarded industry experts from Germany.
DGUV Information 203-078 – Thermal hazards from electric fault arc Guide to the …
To prevent interruption and failure of the energy supply, installations must be protected and maintenance and repair work must be performed. You can also choose between a simplified and a precise calculation method. 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.
