IEC 60060-1 is the foundational international standard for high-voltage test techniques

, defining the general terminology and requirements for dielectric testing of electrical equipment with rated voltages above iTeh Standards The latest version is the fourth edition (IEC 60060-1:2025)

, which replaces the widely used 2010 version with technical revisions to improve clarity and accommodate ultra-high voltage (UHV) testing. iTeh Standards 1. Key Test Types Covered

The standard provides procedures and requirements for four primary types of dielectric tests: iTeh Standards Direct Voltage (DC) Tests

: Defines ripple, test voltage values, and procedures for withstand and disruptive discharge tests. Alternating Voltage (AC) Tests

: Focuses on peak and R.M.S. values, generation methods, and measurement requirements. Lightning Impulse Voltage Tests : Standardizes the i--- Iec 60060-1 Pdf

waveform, defining front time, time to half-value, and tolerances. Switching Impulse Voltage Tests : Standardizes the

waveform (in the 2025 edition) for simulating slow-front transients. Combined & Composite Tests

: Requirements for testing with multiple voltage types applied simultaneously or in sequence. iTeh Standards 2. Core Components of the Standard Description Terminology

Defines discharge characteristics, test voltages, and statistical treatment of results. Atmospheric Corrections

Provides formulas to correct test results for air pressure, temperature, and humidity, ensuring reproducibility across different locations. Test Procedures Detailed steps for Withstand Tests (proving a device can hold voltage) and Disruptive Discharge Tests (finding the breakdown point). Wet & Pollution Tests IEC 60060-1 is the foundational international standard for

Guidelines for testing equipment under rain simulation or artificial contamination (though some specific procedures moved to 3. Major Updates in the 2025 Edition (Edition 4.0)

The 2025 update introduced several critical technical changes: iTeh Standards UHV Extensions

: Extended positive tolerances for lightning impulse front times for equipment above New Switching Impulse Definition

: Introduced a front-time definition for switching impulses similar to lightning impulses, standardizing it to Waveform Calculation : A new informative

provides manual procedures for calculating parameters from graphical waveforms. Usability Improvements Searchability – Allows quick lookup of terms like “1

: Reorganized clauses for combined and composite voltages to make them more accessible for laboratory use. iTeh Standards 4. Essential Related Standards

5. Importance of the PDF Version

3. Test Circuits and Measuring Systems (Clause 7)

Specifies requirements for:

4. Atmospheric Correction Factors (Clause 8)

Because air density and humidity affect breakdown voltage, the standard provides formulas to correct test voltages to standard atmospheric conditions (101.3 kPa, 20°C, 11 g/m³ absolute humidity).
