A glow wire test apparatus is a vital tool that can be used to measure the fire hazard in electrical and electronic devices. It replicates the impact of hot parts able to trigger the ignition of the surrounding insulating material in the faults. The glow wire test is another test considered in a number of safety programs together with other tests that are related to fire like the vertical flammabi...
The surge tester is usually considered based on the maximum voltage but even this end of measurement alone does not say much about the actual performance of the instrument on actual immunity tests. The real or the actual worth of a tester is on the quality of pulses produced by it and also in the dependability of the generator which produces it with thousands of test cycles. In practice devices in...
A humidity test chamber is one of the foundations of stability testing in which moisture-induced degradation is a believable risk. Water vapor undergoes interactions on its level of molecules and interface. It modifies the structure of polymers enhances corrosion speeds up, minimizes the level of insulation and changes mechanical properties during service. Stability programs are thus based on cont...
EMC compliance testing is used to confirm that an electrical or electronic device does not emit objectionable electromagnetic disturbances or does not excessive become susceptible to causes of electromagnetic disturbances in its natural habitat. The principle of its working is based on coexistence. Various equipment should be able to share the electrical infrastructure and spectrum without interfe...
A neutral salt spray test is one of the most popular accelerated corrosion tests used to measure metals and coating on the protective coatings. It is not aimed at exactly simulating real outside conditions but rather produce a controlled and repeatable chloride rich environment that stimulates the corrosion processes very quickly. The ability to initiate and propagate corrosion formation and coati...
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 ...
