As technology advances and electronic devices become more ubiquitous, the impact of lightning surges on electronic equipment is garnering increasing attention. Lightning surges, which refer to transient overvoltages or overcurrents caused by lightning activity on power or signal lines, can cause severe damage to devices. This article explores the effects of lightning surges on electronic equipment...
A surge, also known as a transient voltage or spike, refers to the phenomenon of voltage exceeding the normal operating voltage for a brief moment. Essentially, a surge is a rapid voltage pulse that occurs within microseconds. Common causes of surges include the startup or shutdown of heavy equipment, short circuits, power switching, and the operation of large engines. Surges can potentially cause...
I. Introduction of Surge Generator Surge generators are important equipment in electrical systems. Their main function is to simulate high-voltage pulses or instantaneous voltage fluctuations to test and evaluate the effectiveness of different surge suppression systems. These high-voltage electrical devices mainly serve to prevent transient voltage fluctuations from damaging electrical systems, th...
Introduction Surges, also known as sudden voltage spikes, pose a significant threat to electrical systems because they have the potential to inflict damage to sensitive gear and cause production to come to a stop. Surge generators are required in order to test and assess the efficacy of different surge suppression systems that provide protection against the aforementioned voltage anomalies. In th...
According to the working principle of the simulated surge generator used in electromagnetic compatibility tests and lightning surge generator test, combined with the commonly used 8/20 μs and 10/700 μs test waveforms in current standards, the composition and component parameters of the discharge circuit for simulating different waveforms of surge generator can be obtained through second-order di...
I. Standard for Surge Generator of Electronic Devices The national standard for electro-equipment surge generator is GB/T17626.5 (equivalent to international standard IEC61000-4-5). Surge Generator SG61000 5 II. The standards for lightning surge generator mainly simulate various situations caused by indirect lightning strikes (1) When lightning strikes the external line, a large amount of current...
Lightning and surges are common problems in power systems, especially in high-voltage power equipment.
