Electrical networks face transient overvoltages from lightning strikes and switching maneuvers. Surge arresters protect costly infrastructure like transformers. IEC 60099-5 provides detailed guidance on sizing, locating, and managing these devices. Key Technical Scope

) of the arrester against the lightning impulse withstand voltage (BIL) and switching impulse withstand voltage (BSL) of the protected equipment (e.g., transformers). The standard applies to several varieties of surge

The standard applies to several varieties of surge protection equipment:

Devices using highly non-linear zinc-oxide varistor blocks as defined by the foundational testing guidelines of IEC 60099-4. Detailed Analytical Annexes

Deploying a surge arrester correctly requires rigorous life-cycle monitoring, as degradation can turn a safety device into a phase-to-ground fault hazard. The standard provides practical field diagnostics:
