This is the crucial design parameter. $U_r$ is the maximum permissible RMS value of power-frequency voltage that the arrester can withstand for 10 seconds while conducting rated current (thermal stability).

Compare the protective level of the chosen arrester (its maximum residual voltage) against the rated lightning and switching impulse withstand voltages of the equipment it protects. This step conforms directly to the broader system framework defined in IEC 60071-2 (Insulation Coordination). Technical Comparison of Arrester Types iec 600995 pdf

The . As explained by the IEC, this standard "provides information, guidance, and recommendations for the selection and application of surge arresters to be used in three-phase systems with nominal voltages above 1 kV". It is not a mandatory normative document but offers essential best practices for applying this equipment effectively.

Specifies requirements and tests for metal-oxide surge arresters without gaps for AC systems.
