Testing Principles and Methodology
Surge Immunity Testing Fundamentals
Surge testing evaluates a device’s resilience against transient overvoltages caused by lightning strikes, switching operations, or electrostatic discharge. The SG61000-5 generates two primary waveforms:
- Combination Wave (1.2/50 μs Voltage, 8/20 μs Current) – Simulates lightning-induced surges.
- Ring Wave (100 kHz Damped Oscillatory Wave) – Represents switching transients in power distribution networks.
The generator applies surges through:
- Line-to-Line (Differential Mode) – Between power conductors.
- Line-to-Ground (Common Mode) – Between conductors and ground.
Automated Testing and Synchronization
The SG61000-5 supports automated test sequences, enabling repeatable evaluations for mass production testing in industries such as automotive electronics and household appliances. Phase synchronization ensures accurate testing of three-phase systems in rail transit and power equipment applications.
