DGUV-I 203-077 Arc Energy Analysis

The new DGUV-I 203-077 2021 supersedes its 2012 predecessor. This methodology is used in several EU countries to comply with their regional electrical safety regulations. The development of this new edition of the standard has taken almost a decade of work and provides a guide for the determination of the arc energy in case of an arc event and a guide to the selection of the corresponding Personal Protective Equipment (PPE) for the electrical personnel.

ETAP provides an integrated tool which allows for faster and easier determination of arc energy and PPE selection evaluation. Additionally, generation of deliverables is a key feature available for the labeling of the equipment in the field.

Key Features

Powerful graphical tool for rapid assessment of multiples or batches of ‘what if’ scenarios.
Supported methods for the arc energy calculations:
- DGUV-I 203-077 (Worst-Case).
- Precise method (Schau, H.; Halinka, A.)
Considers the arc characteristics such as arc voltage and resistance.
Considers the effect of the asymmetrical component of the fault current.
Thermal reflectivity factor impact on energy levels supported by PPE.
Electrode material effect.
Flexibility for calculations on 3-phase and 1-phase equipment.
Both AC and DC methodologies are supported as per standard recommendations.
Graphical representation of the results for dynamic risk assessment.
Built-in typical data for common equipment types as per standard.
Supports arc protection level of PPE as per standards:
- VDE 0682-306-1-2
- IEC 61482-1-2

Deliverables Generation

Arc Flash warning labels generation for multiple fault locations without building one-line diagrams.
Import/Export capabilities from third-party databases.
Results report in tabulated format for easier visualization.
Batch process capability to perform calculations for hundreds of fault locations simultaneously.
