Surge Immunity Testing

The SG61000-5 applies standardized surge pulses to assess equipment resilience against transient disturbances. The test involves:

1. Direct Coupling – Surges are injected directly into power or signal lines.
2. Indirect Coupling – Surges are induced via capacitive or inductive coupling.

The 1.2/50 μs voltage waveform and 8/20 μs current waveform simulate lightning-induced transients and switching surges. Tested equipment must withstand these pulses without malfunction or degradation.

Key Testing Configurations

• Line-to-Line Surge Testing – Evaluates differential mode surges between conductors.
• Line-to-Ground Surge Testing – Assesses common mode surges between conductors and ground.
• Combination Wave Testing – Simultaneously applies voltage and current surges to replicate real-world conditions.
