Advancements in technology have revealed that power surges often damage industrial electronic systems. These overvoltages stem from atmospheric discharges like lightning or equipment switching. Transfer impedance varies by interference source location: low when in the same circuit as the equipment, higher for external sources. To simulate both scenarios, a Combined Wave Generator, also called a Surge Generator, is essential. This guide explores surge generators, their specifications, and precisely what a combined wave on a surge generator entails.
A surge generator tests system immunity by producing short, high-voltage surges. Available as pulse current or voltage generators, they deliver high impulse currents for testing equipment like plasma devices and lightning arresters. These grounded, heavy benchtop units ensure safety. For three-phase power lines, they integrate large coupling/decoupling networks, increasing system size.
Activating surge generators creates voltage or current spikes known as surge or combination waves, which can short-circuit or disrupt electrical equipment. A combined wave forms by merging two waves into a composite, accounting for direction, amplitude, and phase. EMC test engineers often rent these for immunity assessments.
Eliminating EMI sources during design and verifying EMC compliance is critical, especially for electrical substations operating in harsh conditions. Surge generators offer diverse output voltage ranges for comprehensive testing.
Power surges from equipment switching or lightning frequently damage industrial electronics. Low transfer impedance in the same circuit produces current pulses; external sources yield higher impedance voltage pulses. Combined wave generators replicate this by outputting voltage open-circuit and current short-circuit.
Combined wave or surge transients arise from lightning or switching. Direct or indirect strikes induce surges. LISUN surge generators stand out, engineered by top experts, positioning LISUN as a global leader in electrical testing equipment.
