Introduction to Surge Immunity Testing<\/strong><\/h2>\n

Surge immunity testing evaluates the ability of electrical and electronic equipment to withstand transient overvoltages caused by lightning strikes, power system switching, or electrostatic discharges. Compliance with international standards such as IEC 61000-4-5, EN 61000-4-5, and GB\/T 17626.5 ensures product reliability across industries. The LISUN SG61000-5 \u00dcberspannungsgenerator<\/a> is a precision instrument designed to simulate these transient disturbances under controlled laboratory conditions. <\/p>\n

Fundamentals of Surge Waveform Generation<\/strong><\/h2>\n

Surge testing requires precise waveform generation to replicate real-world electrical disturbances. The SG61000-5 produces standardized combination waves (1.2\/50 \u03bcs voltage wave and 8\/20 \u03bcs current wave) as defined by IEC 61000-4-5. Key waveform parameters include: <\/p>\n

    \n
  • Open-circuit voltage:<\/strong> Up to 6.6 kV <\/li>\n
