A lighting surge generator has characteristics that are intended to replicate high power transient overvoltage’s that take place as a result of lightning hits and extreme switching activities on power and signal lines. Although most generators declare equally high peak voltage ratings, the actual distinction between them is control system capability and the frequency of support of test waveforms...
Environmental test program qualifies electronic components as a basic condition that they should be able to work under various operating and storing conditions. Electronics in modern application suffer at the ends of the temperature range humidity vibration electrical bias and long duty cycles which increase the rate of most degradation mechanisms solder fatigue corrosion dielectric breakdown and ...
Instrumentation alone does not give an accurate EMI EMC measurement. It is the sum total of a well-adjusted arrangement with the electromagnetic environment working jointly with the test configuration and operator discipline. Minor differences in grounding cable routing or placing equipment can change the results by several decibels that is usually the difference separating a pass and a failure. E...
Impulse voltage generator is one of the basic instruments used to test the insulation strength of high voltage equipment with transient conditions. In contrast to steady state tests (AC or DC) in impulse testing, transient elevated events produced by lightning strikes switching operations and faults of an electrical system are reproduced. These incidences cause severe electrical loads within very ...
A climatic chamber is a major equipment in checking whether components are viable and can perform well in the case of combined temperature and humidity pressure. Contemporary products are used over a wide range of climatic conditions and duty cycles with heat increasing the rate of chemical reactions and moisture corrosion insulation breakage as well as swelling. Reliability programs are thus base...
Salt spray test has also seen widespread use in order to hasten the corrosion processes such that the metal and protective finishes should be tested over practical laboratory duration. Exposure conditions are standardized when the real value of the test is found in the evaluation of results. Assessment methods put visual and quantifiable damage into an engineering choice of material coating method...
EMI-9KB is popularly utilized in compliance and pre compliance laboratories to obtain fine EMI testing, and a repeatability and stability of testing is of utmost significance. In radiated and conducted measurements of small perturbations across the electromagnetic environment can cause a shift of results by multiple decibels. These variations are not in any way related to the equipment being teste...
A salt testing machine is a very important device to test the capability of the industrial coating to withstand corrosive environment during the period of the planned service. In industries where automotive aerospace construction and heavy machinery coating are used, appearance is not considered to only be important but corrosion resistance against chloride caused corrosion is the criteria. Custom...
Abstract In the safety design of electrical and electronic products, preventing the ignition of surrounding materials due to overheating of internal heating elements (such as resistance wires, motor windings) is a crucial issue. The Hot Wire Ignition (HWI) test, as a standardized method simulating such overheating fault scenarios, provides key data for evaluating the resistance to ignition of soli...
