Testing

While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve the safety goals.

This is the second of a two-part series that discusses a numerical methodology that relies on the concept of cumulative equivalent exposure to evaluate contact burn injury thresholds.

Most ESD experts consider CDM testing to be the most critical ESD qualification test for modern integrated circuits. ESD control engineers need to know the charged device ESD robustness of all components passing through their manufacturing line. CDM measurements provide that knowledge.

The history and insight into how the EMC specifications and procedures evolved at one automotive original equipment manufacturer (OEM). Other present-day OEM specifications are more similar than different mostly due to the extensive reference to international standards which these OEMs have taken part in developing (e.g., EMC committees). Knowing this history should help today’s EMC practitioners, especially those new to the discipline, gain some insight into the implementation and limitations of test procedures and when to be flexible in analyzing test results.

RF field probes are specialized measuring instruments with unique specifications and performance characteristics. This article details the main factors to consider in selecting a probe appropriate to your testing needs.

The ubiquitous increase in the use of mains power switching devices has been paralleled by the increase in nuisance tripping of GFCIs and other protection devices. Nuisance tripping can be identified to contain such high frequency signals and these must be properly taken into account when designing proper GFCI operation in this environment.

EV batteries and battery packs are complex systems, requiring a comprehensive design and testing strategy to help ensure safe and efficient electrical power.

The safety hierarchy is a flexible concept that can be helpful in deciding on a final product design. But it can also be a trap for the unwary design engineer. This article will discuss the safety hierarchy concept, how do you comply with its requirements, and what are the problems associated with it?

Are you considering the purchase of an EMC chamber for in-house testing? If so, what factors should you consider for determining if the investment is a wise choice or if the continued utilization of a third-party test facility is the better option?

EMC testing laboratories often have limitations (limited availability, lead times, etc.) that can make it difficult to obtain timely results from routine troubleshooting. Inexpensive test equipment can support efficient and economical in-house EMC troubleshooting.
