Testing and measurement techniques – Surge immunity test



At least 5 positive and 5 negative surges at an angle of 0⁰, 90⁰, 180⁰ and 270⁰ at a repetition rate no faster than 1 per minute, of 1.2/50µs for the voltage and 8/20 µs for the current wave shape surges from a surge generator of 2Ω output impedance for line-to-line on AC/DC power lines and 12Ω output impedance for line-to-earth on AC/DC power lines.
