What is a Lightning Impulse & Why Does It Matter for Power Grids?
A standard lightning impulse is defined by international standards like IEC 60060-1 and IEEE Std 4 as a 1.2/50 μs transient overvoltage waveform, designed to test the Basic Insulation Level (BIL) of electrical equipment against atmospheric lightning strikes.
As an essential part of high voltage testing equipment, conducting a lightning impulse test allows engineers to simulate real-world atmospheric hazards in a controlled laboratory environment. This rigorous simulation helps substation managers, utilities, and apparatus manufacturers validate design margins, verify dielectric strength, and ensure regulatory compliance to eliminate catastrophic field failure risks in critical power grid infrastructure.
