The IEC sometimes allows a free preview of the scope, table of contents, and definitions on their website, though the full technical body requires purchase. (k_2) on humidity.

Understanding this document is essential for power engineers, high-voltage laboratories, and equipment manufacturers. It ensures that high-voltage assets like transformers, switchgear, and cables can withstand real-world electrical stress. Technical Overview of IEC 60060-1

Defines procedures to protect personnel during testing.

High-voltage testing is a crucial aspect of ensuring the reliability and safety of electrical power systems. IEC 60060-1 provides a standardized framework for high-voltage testing, which enables accurate and comparable results. The standard is essential for various reasons:

for AC/DC tests: [ K_t = k_1 \cdot k_2 ] Where (k_1) depends on air density (pressure & temperature), (k_2) on humidity. The PDF provides tables for (k_1) from 0.7 to 1.3 and (k_2) up to 1.1.
