An EM Test surge generator is special equipment which replicates the high-energy transient overvoltage’s a product is likely to experience in the field enabling engineers to conduct consistent surge immunity testing. These generators are intended to model two physically different types of transient events, the high-voltage combination wave, which is fast, short lived and high-voltage and the hig...
The devices of electricity and electronic equipment which are attached to power and signal line are prone to the transient overvoltage occurrence as a result of lightning strike, switching in the grid, and inductive load interrupt. In order to test immunity to these disturbances, a 10kV surge generator that can reproduce controlled high-energy pulses is used to test immunity in laboratories. In pr...
Electronic equipment installed into real-world conditions is often vulnerable to transient overvoltage conditions due to lightning strikes, switching of power grids, interrupting inductive loads, and electrostatically couple with impractical ground. To ensure that the products will not fail and get away during such events, engineers use a surge wave generator that recreates standardized high-energ...
The contemporary electronic equipment should be usable in the conditions when electric problems cannot be avoided. Any activities involving switching of power, lightning-induced transients, relay activities and inductive loads trigger voltage surges on sensitive circuits in the short term that may cause circuit brown-out or damage. A burst surge generator is a specially constructed device to recre...
The modern power distribution networks have been based on the use of protective devices that do not fail when responding to sudden changes in electricity. The origin of these transients can be lightning, switching of loads with high inductance, grid noise, capacitor bank energization or equipment faults. Surge protecting elements, insulation systems, arrestors, breakers in a distribution, and rela...
One of the most expensive and disruptive faults that have occurred in electrical systems is the insulation failure. Regardless of the application and the utility transformers, switchgear assemblies, rotating motors, GIS panels, surge arrestors or distribution relays, irrespective whether the dielectric systems have failed, this is reporting directly to extended outages, fire hazards, damaged equip...
Abstract In fields such as electrical and electronic products, new energy, and communications, lightning surge interference faced by equipment is a key factor leading to product failures and performance degradation. EMC (Electromagnetic Compatibility) compliance certification is a crucial threshold for products to enter the market. This paper takes the LISUN SG61000-5 Surge Tester Manufacturers...
Abstract In the actual operating environment of electrical and electronic equipment, high-energy transient interference caused by natural lightning induction and large-capacity inductive-capacitive load switching poses a serious threat to the stable operation of equipment power cords and internal connecting wires. As a core testing device, the surge generator working principle can simulate such i...
Abstract With the increasing complexity of electrical and electronic systems, the reliability of power supply lines and internal connecting cables under transient interference has become a critical concern. Natural lightning-induced surges and high-capacity inductive-capacitive load switching can generate high-energy transient disturbances, which may cause irreversible damage to sensitive componen...
Introduction In modern electrical and electronic systems, transient overvoltages, commonly known as surges, pose a significant threat due to their potential to cause catastrophic equipment failure or operational disruptions. These surges can stem from lightning strikes, switching operations in large-scale equipment, or faults within power grids. Surg simulators, as pivotal tools in electromagnetic...
Abstract Electromagnetic Compatibility (EMC) testing plays a pivotal role in ensuring that electronic devices operate reliably within their intended electromagnetic environment without causing or being affected by electromagnetic interference. One of the key pieces of equipment used in EMC testing is the lightning surge generator provided by LISUN Electronics Co., Ltd. This device is specifically ...
Abstract With the rapid advancement of power electronics technology, electric motors have become indispensable components across various industries including manufacturing, transportation, and household appliances. However, during operation, these motors are often subjected to transient overvoltage events known as surges. These surges can originate from lightning strikes, switching operations, gri...
