What is a Surge Generator?

Surge Generators are used to perform surge immunity testing in accordance with standards such as IEC 61000-4-5. These tests simulate high-energy transient events caused by lightning strikes, power system switching, and load changes that can propagate through electrical networks. The generators produce combination waveforms, typically defined as 1.2/50 µs voltage waveforms and 8/20 µs current waveforms, which are applied to the equipment under test to assess its ability to withstand such disturbances.

Key performance parameters of Surge Generators include output voltage and current levels, waveform accuracy, source impedance, and coupling configurations. These systems are capable of generating surge voltages ranging from a few hundred volts to several kilovolts, along with corresponding high-current pulses. Coupling and decoupling networks are used to inject the surge into power lines, communication lines, and other interfaces while protecting auxiliary equipment. Precise control of waveform shape and timing is critical to ensure compliance with test standards and to achieve repeatable results.

Modern Surge Generators incorporate programmable test sequences, adjustable output levels, and built-in coupling networks for different test configurations such as line-to-line and line-to-ground testing. Many systems support automated operation, remote control, and integration with EMC test software to streamline testing workflows. Advanced safety features, including interlocks and monitoring systems, are implemented to ensure safe operation during high-energy testing.

Surge Generators are used in EMC compliance testing, product certification, and design validation across industries such as industrial equipment, telecommunications, automotive electronics, consumer devices, and power systems. They help identify vulnerabilities to high-energy transients and support the development of robust products capable of withstanding real-world surge conditions.
