Impulse Current GeneratorZC-522-20A

The ZC-522-20A Impulse Current Generator is specifically designed to verify the withstand capabilities of electrical equipment and components under extreme transient current surges. It precisely simulates ultra-high-energy current impulses associated with scenarios such as direct lightning strikes and short-circuit faults, comprehensively addressing the reliability testing requirements for surge arresters, fuses, power semiconductors (e.g., IGBT and SiC modules), and new energy systems (including energy storage batteries and charging piles). By providing a full-lifecycle, high-current impulse verification solution—spanning from R&D through to certification—for power equipment manufacturers, lightning protection device suppliers, and third-party testing agencies, this generator facilitates the optimization of equipment short-circuit withstand strength, enhances grid resilience and the safety levels of new energy systems, and empowers the construction of a highly reliable power ecosystem.
