The IEC 60099 series is divided into multiple parts, each covering a specific type of surge arrester or application.

The standard expanded its documentation on line-discharge calculations and estimation tools. This update enables engineers to accurately predict the thermal energy stress generated by varying line lengths, surge impedances, and network configurations. 3. Step-by-Step Selection Methodology

IEC 60099-5:2018 is the latest edition of the international standard providing comprehensive recommendations for the selection and application of surge arresters iec 600995 pdf

Understanding the latest updates in the standard is necessary when working with an updated document. The third edition (2018) introduced sweeping technical modifications to align with the core changes implemented in IEC 60099-4. Shift from Line Discharge Classes to Charge Ratings

Defines what types of systems (AC, DC, distribution, transmission) the document applies to.

)—the peak voltage drop across the arrester during a surge—remains safely below the basic insulation level (BIL) of the protected equipment, such as power transformers. The IEC 60099 series is divided into multiple

: It covers gapless metal-oxide arresters, gapped designs (rated 52 kV and less), and externally gapped line arresters (EGLA).

The standard has evolved. The most widely referenced version is IEC 60099-5:2018 (Edition 3.0). This edition replaced the 2000 version and its amendment, incorporating significant changes regarding high-voltage arresters and modern Metal-Oxide (MO) technology.

By systematically applying the guidelines found within IEC 60099-5, utilities and industrial plants can guarantee the long-term reliability of their high-voltage grids against nature's most unpredictable surges. IEC 60099-5:2018 is the latest edition of the

You can purchase the IEC 60099-5 standard from the IEC website or other authorized distributors. The standard is available in PDF format, which can be downloaded immediately after purchase.

Bidding and procurement documents match global industrial benchmarks.

Here's a brief guide to get you started:

The standard mandates minimum protection margins to account for physical distance and lead inductance:

However, choosing the right arrester is a complex task. This is where becomes indispensable. What is IEC 60099-5?
