IEC 60099-5 is the bridge between the laboratory testing of a surge arrester and its real-world application on the grid. It transforms the raw data from the manufacturer (Part 4 tests) into a practical specification (Part 5 application).

By following this guide, you should have a better understanding of IEC 60099-5 and its significance in the selection and application of surge arresters.
