1. Subject Matter Analysis

IEC 60060-1: High-voltage test techniques – Part 1: General definitions and test requirements. This is a foundational international standard used in electrical engineering. If you are drafting a technical paper, a test plan, or a summary based on this standard, it must address the following key areas:

• Definitions: Does the draft clearly define terms like "test voltage," "standard lightning impulse," and "switching impulse"?
• Test Voltages: Does it specify the requirements for DC, AC, and impulse testing?
• Peak Values & Tolerances: Does it accurately list the standard voltage levels and the permissible tolerances (e.g., lightning impulse front time $1.2 \mu s \pm 30%$)?
• Atmospheric Corrections: A critical component of IEC 60060-1 is correcting test voltages based on temperature, pressure, and humidity. Does your draft include the formulas for correction factors ($K_t$)?

Practical Application: How to Perform a Test Using IEC 60060-1

Let’s walk through a real-world example: Impulse voltage test on a 245 kV power transformer bushing.

1. Open your IEC 60060-1 PDF to Clause 6 (Impulse voltages).
2. Select waveform: Lightning impulse 1.2/50 µs, peak voltage per product standard (e.g., 850 kV BIL).
3. Set up circuit: Follow Clause 7.2 for a resistive voltage divider and digital recorder.
4. Apply corrections: Measure ambient air pressure, temperature, humidity. Apply Clause 8.2.3 formula to adjust test voltage.
5. Execute sequence: Apply 15 impulses per Clause 9.2.1. Pass if ≤2 disruptive discharges occur.
6. Document everything: Include PDF page references in your test report (e.g., "Corrected per IEC 60060-1:2010, Clause 8.2").
