Accessibility of live parts To reduce the likelihood of unintentional contact that can involve a risk of electric shock from an uninsulated live part or film-coated wire, an opening in an enclosure shall comply with either (a) or (b): a) For an opening that has a minor dimension(see Clause 4.2.5.5) less than 25.4 mm (1 in), such a part or wire shall not be contacted by the probe illustrated in Fig...
Introduction: A goniophotometer is a high-tech device for determining the angle of illumination from a given source. It is vital in the fields of lighting design, R&D, and quality assurance. Accurate and trustworthy readings are the result of a goniophotometer’s several parts working in concert. This article will examine the components of a goniophotometer, their roles, and their signifi...
Introduction Electric vehicles (EVs) are increasingly becoming the vehicle of choice for those who are worried about the effect their actions will have on the environment. Along with the meteoric rise in popularity of electric vehicles (EVs), there has been an accompanying explosion in the need for a charging infrastructure that is both trustworthy and effective. However, when these charging techn...
Introduction Environmental chambers reliability testing relies heavily on temperature cycling. Temperature cycling is a method of testing a product’s or component’s resilience and performance in severe temperatures by repeatedly exposing it to temperature swings to mimic real-world situations. The electrical, automotive, aerospace, and telecommunications sectors are just some of the ma...
Introduction The widespread connectivity and seamless data interchange made possible by the IoT have dramatically altered the ways in which we use technology. But as the IoT grows, it confronts serious problems, including electromagnetic interference (EMI). IoT networks are vulnerable to EMI, which may cause communication breakdowns, data corruption, and poor system performance. EMI test receivers...
