Research For The Calibration Method Of Surge Testing Instruments

Surge signal is simulated in the role of the equipment in building the indirectlightning phenomenon, its the purpose of the experiment is to test electric andelectronic equipment for from lightning (mainly simulates the indirect ray) and highpower load or switch transient, and other types of perturbation resistance ofdisturbance. Electronic products of surge interference ability is the product is normalwork, or can not be products of lightning damage an important signal ofelectromagnetic compatibility indexes. Through the test, to test and make sure that theelectronic products of lightning surge interference ability. In the electromagneticcompatibility testing, we use the surge equipment to produce pulse disturbance, andput the interference waveform into test of electric products, and the products theanti-interference ability of the measure.Surge of the accuracy of the output signal equipment directly affect the accuracyof the measurement results and repeatability, so in this equipment calibration is veryimportant. This paper the research content as follows:[1] paper first reviews the current surge equipment calibration technology at homeand abroad present status of these methods and existing problems of this paper.[2] to the national standard GB/T17626.5-2008and international standard IEC61000-4-he05as the foundation, the related test device, the design of the systemsolutions. According to the test system, equipment calibration data collection;Through the analysis of data, discuss the merits of the existing calibration methods,and puts forward the ideas and more reasonable calibration through tests to verify.[3] by the deviation of calibration data analysis reasons, through the design of testconditions to verify these analysis.[4] then discusses a surge of equipment parameters change, calibration data out ofthe situation.[5] finally to the above to the analysis of the surge equipment calibration methoduncertainty of analysis.Through the study, not only to further improve the relevant personnel to teststandard laboratory of understanding, more important is to surge equipmentcalibration technology further research to provide ideas, really do seem not only, alsoknows nothing.
