: Evaluation of insulation performance under constant voltage.

Adhering to IEC 60060-1 is vital for manufacturers and operators of transformers, switchgear, and insulators to guarantee equipment reliability. Mismatches between standards (e.g., using an IEC-rated device in an IEEE-governed grid) can lead to and expensive project delays.

: Testing for power-frequency withstand, typically involving a one-minute exposure to elevated voltages. i--- Iec 60060-1 Pdf

For professional access to the full technical details, you can obtain the official document from the IEC Webstore or authorized retailers like iTeh Standards . IEC 60060-1:2025

: For switching impulses, the term "time-to-peak" has been replaced with " front time " to match lightning impulse terminology. Standard Switching Impulse : Redefined as 170/2 500 µs . Standard Switching Impulse : Redefined as 170/2 500 µs

The standard is the global foundation for high-voltage (HV) testing, providing essential definitions and requirements to ensure electrical equipment can safely handle extreme voltage levels. Formally titled "High-voltage test techniques - Part 1: General definitions and test requirements," it applies to any equipment with a highest rated voltage ( Umcap U sub m ) above 1.0 kV AC or 1.5 kV DC . Core Scope and Applications

The standard outlines the procedures for several critical dielectric tests: : Testing for power-frequency withstand

The latest revision, IEC 60060-1:2025 , introduced significant technical changes to improve usability and accuracy:

: Simulating rapid transients like lightning and switching surges.
