is a foundational international standard that defines the procedures, definitions, and requirements for high-voltage testing of low-voltage equipment. Developed by the International Electrotechnical Commission (IEC) , it serves as the primary technical guide for ensuring that low-voltage devices—those rated up to
The core objective of IEC 61180-1 is to provide a standardized framework for performing dielectric tests. These tests are critical because they verify that the insulation of a product can withstand overvoltages, such as those caused by lightning strikes or internal switching surges, without suffering a disruptive discharge.

IEC 61180-1 outlines the specifications for generators used to produce test voltages. It sets limits on the characteristics of the voltage waveform to ensure the stress applied to the test object is consistent and measurable.
❌ Applying AC rms voltage where impulse is required – different stress mechanisms. ❌ Ignoring waveform tolerance – a 1.5/40 μs impulse is not valid. ❌ Testing without a calibrated measuring system – results unrepeatable. ❌ Using wrong polarity – some insulation (e.g., polluted surfaces) is polarity-sensitive. ❌ Not correcting for altitude – above 2000 m, test voltage must be reduced (or air gaps increased). is a foundational international standard that defines the
The standard provides detailed criteria for the generation and measurement of test voltages to ensure reproducibility and safety.
This standard is critical for anyone designing, testing, or certifying (typically below 1 kV AC or 1.5 kV DC) that must withstand high-voltage stresses (e.g., surges, transients, or dielectric tests). Would you like a practical example of calculating
: For impulse tests, clauses 6.1 and 6.2 of the standard specify the exact rise time and duration of the voltage surge to be applied.
