Introduction In order to guarantee the dependability, safety, and performance of surge generators, it is essential that they correspond to international standards in the field of electrical systems and surge protection. Surge generators that are compliant with these standards serve as a quality indicator since they may be used with other electrical devices and systems without any issues. This arti...
Temperature and Humidity Chamber is used to test the material structure and composite material, can withstand the range in the continuous environment of extreme low temperature or extreme high temperature, and to test the chemical change of thermal expansion and contraction caused by it. A kind of testing mechanical instrument which can accurately test temperature and humidity. In addition, the h...
The destruction of materials in nature and humidity in nature causes difficult economic losses every year. UV accelerated weather test machines can reproduce the damage caused by sunlight, rain and dew. The equipment is exposed to the exposure of the tested material in the controlled sunlight and the interactive cycle of moisture, and at the same time improve the temperature to test it. The device...
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 ...
