) of the arrester against the lightning impulse withstand voltage (BIL) and switching impulse withstand voltage (BSL) of the protected equipment (e.g., transformers).
This standard is the authoritative guide for selecting and applying surge arresters (specifically metal-oxide surge arresters without gaps) to protect electrical equipment against overvoltages. Includes new Annexes H and I for cross-calculating
IEC 60099-5:2018 provides comprehensive recommendations for the selection and application of gapless metal-oxide, gapped, and external series gap surge arresters in high-voltage three-phase systems. The standard covers technical parameters like residual voltage, installation conditions, and serves as guidance for systems over 1 kV. Access the official publication at IEC Webstore .
