Low voltage testing

Guidelines for Low Voltage Tests

This article looks at the various test situations you may encounter and gives our recommendations for the appropriate low voltage testing. Test Situation Recommendation No testing This is justified when testing does not find sufficient defects to justify the additional cost in testing. This assumes the process of manufacturing assemblies can be expected to stay…

AC Hipot Testing

Hipot testing involves using a high potential (voltage) to test insulation. A hipot test can be very useful in helping you develop a process that builds high quality cables and wire harnesses. There are two popular hipot voltage sources: DC and AC. This article introduces some of the concepts you’ll find in AC hipot testing.…

shielded cable assembly

Testing Shielded Cable Assemblies

Why do cables have shields? To prevent signals in cables from radiating and causing interference. To prevent outside signals from affecting signals inside the cable. To maintain controlled impedance so that fast-changing signals can travel long distances without electrical “echos.” Testing Recommendations Shielded cable assemblies have an increased chance of defects in the manufacturing process.…
