IEC 61180-1 outlines three primary types of high-voltage tests used to evaluate insulation integrity: 1. Direct Voltage (DC) Tests
The standard provides a framework for several types of dielectric tests: IEC 61180:2016
It specifically applies to equipment with a rated voltage not exceeding 1 kV AC or 1.5 kV DC. It outlines the types of voltage stresses that low-voltage equipment might face during its operational lifespan and defines how to replicate those stresses safely and accurately in a laboratory environment. Why the Standard Matters
AC power-frequency tests simulate the continuous operational stress and temporary overvoltages that equipment faces on the electrical grid. Typically performed at 50 Hz or 60 Hz. Waveform: Must be substantially sinusoidal. iec 61180-1 pdf
IEC 61180-1 is titled "High-voltage test techniques for low-voltage equipment – Part 1: Definitions, test and procedure requirements." It establishes uniform requirements for high-voltage testing of equipment rated for low-voltage systems (typically up to 1000 V AC or 1500 V DC).

Q: What is the purpose of IEC 61180-1? A: The purpose of IEC 61180-1 is to provide guidelines for high-voltage testing, including test procedures, safety precautions, and equipment requirements.
The target voltage level required by the specific product standard.
An insulation system passes an IEC 61180-1 test if it withstands the specified voltage without disruptive discharge. The standard differentiates between different types of insulation failure: Why the Standard Matters AC power-frequency tests simulate

Impulse tests simulate atmospheric disturbances (lightning) or heavy switching transients. This is one of the most critical sections found in the IEC 61180-1 PDF. Defined by a wave shape. Front Time ( T1cap T sub 1 ): , representing how fast the voltage rises to its peak. Time to Half-Value ( T2cap T sub 2 ): , representing the decay time to 50% of the peak value.
Localized electrical discharges that only partially bridge the insulation between conductors (often covered under separate specialized standards but monitored during high-voltage setups).
