61180-1 — Iec

IEC 61180-1 does not exist in isolation. It is frequently referenced by other safety and product-specific standards:

The standard provides detailed criteria for the generation and measurement of test voltages to ensure reproducibility and safety.

: Simulates transient overvoltages. The standard specifically details the iec 61180-1

: To maintain integrity, the standard emphasizes the use of effective screening to protect measuring systems from electromagnetic interference. Relationship with Other Standards

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 does not exist in isolation

—possess the necessary dielectric strength to operate safely under normal and transient electrical stress.

This standard applies to equipment with rated voltages up to and including 1 000 V a.c. (alternating current) and 1 500 V d.c. (direct current). It covers various forms of high-voltage testing, including: The standard specifically details the : To maintain

❌ 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).

The standard specifies requirements for the measurement systems used to record the peak values of test voltages. This includes the use of suitable voltage dividers and measuring instruments with appropriate accuracy classes.
