1. Test standards for electronic equipment lightning waves The national standard of the lightning waves of electronic equipment is GB/T17626.5 (equivalent to international standard IEC61000-4-5). The standard is mainly to simulate the various situations produced by indirect lightning strikes: (1) Lightning strike the middle and external lines, and a large amount of current flows into the externa...
Introduction By giving meticulous attention to the design of a building’s lighting, one may increase not only the building’s aesthetic value but also its functionality and mood. Techniques for precise measurement and analysis, such as goniophotometry, are an absolute need in the realm of architectural lighting if one is to achieve the desired outcomes from the use of lighting. In this ...
The Sand Dust Test Box is designed for assessment of two levels of protection standard specified by the enclosure protection standard, which is mainly used to simulate the destruction of sandstorms on military equipment, locks, motor and vehicle components, sealers, power meters and other products. The advantages of the sand dust test box are that it has three functions of blowing dust, blowing sa...
Introduction Accurate spectrum measurements and the characterization of light sources and materials are often performed using high precision spectroradiometer integrating sphere systems. Consistent lighting is an important consideration for the accuracy and precision of these devices. In this article, we examine how uniform illumination affects the precision, repeatability, and efficiency of integ...
An integrating sphere collects electromagnetic radiation from a source usually external to the optical device, usually for flux measurement or optical attenuation. Radiation introduced into an integrating sphere strikes the reflective walls and undergoes multiple diffuse reflections. Integrating Sphere Because of the frequent use of integrating sphere, many customers who have purchased spectromete...
Introduction Electronic components are the backbone of contemporary technology, and many different fields depend on their dependability and efficiency. Electronic components are sensitive to temperature and humidity, two environmental conditions that may shorten their lifespan and compromise their performance. In this article, we will examine how changes in temperature and humidity may impact the ...
Introduction: To measure the efficiency and durability of electronic parts and systems, electrostatic discharge (ESD) testing relies heavily on ESD guns. Understanding and following suitable calibration standards for ESD guns is essential for obtaining trustworthy test results. This article gives a comprehensive introduction to ESD gun calibration, including topics such as why calibration is neces...
Electrical Safety Test is used for high voltage components and device insulation testing (with AC and DC withstand tester), such as silicon stacks, etc. It is mainly used to detect whether the product has leakage, whether it is well grounded, whether it will harm personal safety and special instruments, the main testing items are voltage, leakage current, insulation resistance and grounding resist...
Introduction: The term “electromagnetic compatibility” (or “EMC”) refers to the ability of electrical equipment to function without causing interference to one another or to other systems. When evaluating the electromagnetic compatibility (EMC) of a device, EMI test receivers are important. Physical testing with EMI test receivers is standard but may be time-consuming and e...
