Arc Flash Calculation (AFH) Siemens PSS SINCAL Protection Modules

Arc Flash Calculation (AFH)

Requirements and Use Cases

Employers are obliged by health and safety laws and electric codes to assess working conditions and take appropriate measures to ensure safe working conditions. When working on or in the vicinity of live system parts, service personnel are exposed to the risk of arc flashes. According to accident statistics, arcing faults and their consequences are major causes of injuries in the electrical industry. The following measures help to reduce risks to persons:

• Risk assessment regarding arc flash events
• Definition of safety distances
• Improvements to the network and protection
• Provision of suitable personal protective equipment
•  Affixing of warnings to systems

Solution

The module for arc flash analysis (AFH) in PSS®SINCAL enables the calculation of arc flash energy and other parameters and supports the user in optimizing existing equipment. The typical steps of an arc flash analysis are:

• Calculation based on a network model for 3-phase short-circuit current calculations with detailed simulation of the protection devices and system configurations
• Arc flash calculation and analysis based on current national and international regulations (DGUV Information 203-077 or IEEE 1584 and NFPA 70E)
•  Display of results in network plans, reports and user-definable warning signs
•  Development of measures for risk minimization based on the calculation results
