(If, at the time the order is placed, the above standard is in a transition period between two versions, the newer version shall apply.)
Requirements:
- Information on the plant situation provided by the client by means of a fully completed and signed questionnaire
- Indication of the earth resistivity ρE. A
An on-site measurement according to the WENNER measuring method is expressly recommended. Alternatively, the worst case can be considered for the different soil types. - Provision of drawings/pictures of the building/plant to be
protected and, if applicable, the existing earth-termination system
in electronic form in the following data formats:
• 2D: .dxf, .dwg, .pdf, .skp
Specification:
Analysis of a dimensioned earthing concept with regard to step voltage in the event of lightning interference, including overview and detailed drawings as well as an explanation of the situation and planned measures.
- Optional: Conducting a fee-based risk analysis (S19277)
- Optional: Fee-based design of the earth-termination system for lightning protection (S19295)
Scope:
- Examination of the current situation without measures to protect people
- Simulation results earth potential rise
- Simulation results step voltage
- Design of measures to protect people
- Determination of safe areas
- Preparation of the documentation of the earthing system with measures to protect people (drawings, descriptions)
