: Testing for power-frequency withstand, typically involving a one-minute exposure to elevated voltages.
The dielectric breakdown strength of air depends heavily on its density and humidity. Because high-voltage laboratories exist at various altitudes and in different climates worldwide, test results must be standardized.
is the foundational international standard for high-voltage (HV) test techniques , establishing the general definitions and requirements for dielectric testing of electrical equipment. It is primarily applicable to apparatus with a highest voltage ( Umcap U sub m ) exceeding 1 kV AC or 1.5 kV DC. Scope and Core Objectives

Standards often receive minor technical corrigendums or amendments that alter critical math formulas or tolerance windows.
Precise definitions for lightning impulse (1.2/50 μs) and switching impulse (250/2500 μs) shapes, including tolerance on peak voltage, time-to-front, and time-to-tail. Where to Secure the Official IEC 60060-1 PDF
Using a legally obtained copy of a standard ensures you are referencing the correct, finalized text. Many websites offering "free" downloads host: Precise definitions for lightning impulse (1
Simulates transient overvoltages caused by atmospheric lightning strikes. The standard defines the as a
These tests replicate slower transients created by opening or closing circuit breakers within the transmission network. Formally defined as a transient profile. Front Time ( T1cap T sub 1 ): Mandated at
DC testing is primarily deployed on high-voltage direct current (HVDC) transmission equipment, cables, and systems exhibiting massive capacitance. IEC 60060-1 mandates the permissible ripple factors and details how space charges accumulate within solid insulation matrices over extended exposure windows. 2. Dielectric Tests with Alternating Voltage (AC) IEC 60060-1 provides the foundational language

IEC 60060-1 provides the foundational language, test definitions, and general requirements essential for consistent, safe, and reproducible high‑voltage dielectric testing across electrical equipment types. Practitioners should use it alongside product‑specific standards to design test programs, interpret results, and certify equipment for field service.
IEC 60060-1, “High-voltage test techniques — Part 1: General definitions and test requirements,” defines the principles, terminology, and general requirements for electrical high‑voltage testing. It provides a standardized framework for specifying and performing routine, type, and special dielectric tests on electrical equipment and installations to determine whether insulation and clearances meet design and safety expectations under specified conditions.
Procedures for testing equipment under two or more different voltage stresses simultaneously (e.g., AC + Lightning Impulse) . 🛠️ Key Technical Changes in the 2025 Edition
