Conformity assessments for arc flash safety according to DIN CLC IEC/TR 62271-307 VDE 0671-307 and DIN IEC/TR 62271-312 VDE 0671-312
Modifications to switchgear or factory-built substations are common practice. However, almost every modification invalidates previously performed arc flash type tests. As the operator, you are responsible (according to the German Ordinance on Industrial Safety and Health - BetrSichV) for demonstrating that personal safety is still guaranteed.
This is precisely where we, as an independent engineering firm, offer crucial support. We don't sell new systems – we provide objective, technical certainty.
We assess the conformity of your modified systems according to recognized engineering standards:
TR 62271-307: Conformity of arc flash safety after a modification
For existing switchgear (e.g., according to IEC 62271-200), the crucial question is: After the retrofit/RecoFIT® (e.g., replacement of a circuit breaker), is the system still compliant with the arc flash test that was valid before the modification?
Our service: We conduct the engineering assessment and verify whether the arc flash safety of the modified system is still guaranteed.
TR 62271-312: Validity of the type test
Even minor modifications to factory-built substations (tested according to IEC 62271-202) often lead to deviations from the tested design.
Our service: We assess whether the changes to your modified substation (e.g., different components, ventilation, pressure relief ducts) are implemented in such a way that they conform to a type-tested substation.
Your advantages:
- Cost-effectiveness: The costs for transporting and conducting new type tests can be many times higher than those for a conformity assessment.
- Objectivity: We are manufacturer-neutral. Our goal is the safe and economical continued operation of your existing system, not the sale of a new one.
- Legal certainty: You will receive comprehensive documentation from us as proof of your operator responsibility and as an essential component of your risk assessment.
- Clear answers: We'll tell you definitively whether your modified system still meets the required safety objectives or what technical measures are necessary.
