This section defines fundamental terms:
| Voltage type | Definition | Parameters | |--------------|------------|-------------| | | Ripple ≤ 3% (for dry tests) | Average value | | Alternating voltage | Frequency 45–65 Hz | Peak/√2, distortion ≤ 5% | | Lightning impulse (1.2/50 µs) | Front time T₁ = 1.2 µs ±30%, Half-value time T₂ = 50 µs ±20% | Peak overshoot ≤ 10% | | Switching impulse (250/2500 µs) | Front time = 250 µs ±20%, Half-value time = 2500 µs ±60% | – | IEC 60060-1:1989 - High-voltage test techniques
While both standards serve similar purposes, they differ in regional focus and specific methodologies: IEC 60060-1 IEEE Std 4 Global / International North America Standard Temperature Rise Time Calculation 30%-90% of peak (x1.67) 10%-90% of peak Transformer Testing Requires full and chopped wave tests Chopped wave is often optional Voltage Levels Refers to LIWV Refers to BIL Why This Standard Matters
IEC 60060-1 is a standard that outlines the requirements for high-voltage test techniques, including test equipment, measurement methods, and safety precautions. The standard is part of the IEC 60060 series, which deals with high-voltage testing techniques. Specifically, IEC 60060-1 provides guidelines for tests performed on high-voltage equipment, such as power transformers, switchgear, and insulators. The standard is part of the IEC 60060
IEC 60060-1 does not prescribe detailed test circuits for every device; rather it sets the baseline requirements so other product‑specific standards can reference consistent language and test acceptance criteria.
The International Electrotechnical Commission (IEC) first published IEC 60060-1 to unify how high-voltage tests are performed across different countries and industries. The most current version at the time of writing is , which replaced the 1989 edition.
