as defined in IEC 60099-4.
The active edition () introduced several vital changes that replaced the 2013 version. Understanding these developments is essential for infrastructure compliance: Line Discharge Classes vs. Charge Transfer Classifications
The primary standard for the selection and application of surge arresters is . The current version is the 2018 edition , which provides critical guidance for three-phase systems above 1 kV. 📄 Accessing the Standard
To ensure you are looking for the correct document, you need to know the edition history. Using the wrong (withdrawn) edition could lead to non-compliance with modern safety standards.
: To define residual voltage limits and arrester ratings.

The standard covers several types of high-voltage surge arresters:
The standard provides extensive engineering guidance to system designers, utility operators, and hardware manufacturers. It is specifically built for three-phase systems with nominal voltages . Rather than establishing manufacturing parameters (which are governed by other parts of the IEC 60099 series), Part 5 establishes the formulas, diagnostic methods, and environmental margins required to safely deploy these protective devices in real-world environments.
