There are provision for risk analysis in IEC standards. It is to determine the need for installation of a surge protection device (SPD) in order to protect the low-voltage electrical installations from overvoltages caused by atmospheric phenomena and the like. However, scattered many related standards, the lack of details are not easy to apply it in the field. We investigated the relevant domestic and international standards for applies to the international standards in domestic. And we proposed the flow chart for determining the need for protection of the low-voltage electrical installations from overvoltage due to atmospheric phenomena and it set the appling target facility.

Recently, IEC published new standards about the requirements and tests for lightning protection system(LPS) components. If components are used for LPS, they should comply with the IEC standards. This paper, we collected six specimens for the metallic connection components using in domestic, and it tested for withstand lightning current which according to the IEC 62561-1. As a result, only one specimen meet this performance requirement. The specimen is the metallic connection component with four bolts fixed. Therefor, when designing of LPS in domestic, the metallic connection components shall be taken into account for the selection of the withstand lightning current. In addition, we need to develop for LPS components product and the national standards.
