IEC TR 61117:1992 PDF (Not Available)

The IEC TR 61117:1992 standard outlines a methodology for evaluating the capability of partially type-tested assemblies to withstand short-circuits. It serves as a technical report and provides guidance on extrapolation techniques that can be used to assess the short-circuit strength of PTTAs based on type tests.

The standard emphasizes the need for reliable and accurate evaluation of the short-circuit withstand strength of PTTAs, which are designed to accommodate various electrical components. By using the extrapolation method described in the standard, manufacturers can determine the short-circuit strength of partially tested assemblies without the need for conducting expensive and time-consuming tests on every individual assembly.

The IEC TR 61117:1992 standard plays a crucial role in ensuring the safety and reliability of partially type-tested assemblies. It provides a standardized approach for assessing the short-circuit withstand strength, which is a critical factor in determining the operational safety of electrical systems.
