Transformer preventive testing, a crucial component of power equipment operation and maintenance, has long been given priority by the state. Practical experience suggests that following inspection regulations enables the inspection to make full use of its role and safeguard the safe operation of power equipment. With the enhancement of insulation level and the continuous advancement of computer te...
The High Temperature Pressure Jet Waterproof Test Chamber is an important experimental equipment, usually made of materials such as stainless steel or domestic steel plates. It can simulate high-temperature and high-pressure conditions in real environments, and conduct reliability testing and performance verification on products in experiments. Its main function is to spray high-pressure and high...
Capacitance refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According ...
Photometric Testing is an important step in ensuring the intensity and distribution uniformity of street lights. The luminance measurement is a commonly used testing instrument that can measure the photometric distribution of street lights and provide accurate data analysis. This article will discuss the methods and steps of using a luminance measurement for Photometric Testing, as well as some c...
This article briefly explores the causes and consequences of ESD and EMI in mobile audio systems. It then discusses the use of ESD suppressors and EMI filters to mitigate these threats. Finally, it compares three current solutions. Modern materials and technologies have led to the frequent occurrence of electrostatic discharge (ESD) and electromagnetic interference (EMI), which pose significant ri...
With the development of technology and increasing environmental awareness, people are paying more attention to the environmental friendliness of products. RoHS (Restriction of Hazardous Substances) is a regulation issued by the European Union that aims to restrict the use of hazardous substances in electronics and electronic equipment to protect human health and the environment. RoHS testing refer...
We know that the quantification of color and light is in an abstract sense, so the differences in color and other physical differences are distinct. For example, when we use a measuring stick to measure the length of an object, people often arbitrarily divide it into uniform small segments. Even small lengths that cannot be distinguished by the human eye can be judged by measuring tools. But when ...
Electrical Safety Withstand Voltage Test Standards： Electrical Safety Withstand Voltage Test is an important indicator for measuring the insulation performance of electrical equipment, and its effective measuring standards are: For general test equipment, leakage current values between the spark wire and the shell can be measured, the basic standard requires two times the working voltage plus 10...
What is Hot Wire Test? Hot wire test is a common experiment methodology that is used to study the combustibility and thermal stability of materials. By placing the material above the hot wire and heating the hot wire, it is possible to evaluate the fire hazard and fire protection performance of the material by observing whether the material is ignited and the burning behavior after ignition. Prin...
