When cables/harnesses consist of only wires and connectors, the risk of damage to a good assembly in a properly structured test is small. But what happens when the cable/harness includes components such as resistors, capacitors, diodes, and perhaps even IC's? Learn more in our newsletter this month. Also, we found an interesting video clip that shows what very high voltage together with high current looks like.

Will You Damage your Components During a High Voltage Test?

Do you risk damage to component parts such as diodes, resistors, capacitors, transistors, LED's and IC's when they are embedded in your assembly that is to be tested with high voltage? Voltage implies a difference in potential between two points. If the tester applies voltage across two or more component leads, you risk damaging these components. Cirris testers prevent the application of voltage across components that have been included in the test program. But, if those components are not part of the test program they may be at risk. A more serious problem exists for many non-Cirris testers that cannot be programmed to protect your components. For more information and a brief video about such testing see:

Spectacular video of "Very High" Voltage and Current

Sometimes customers ask us "what current do you use for the hipot test?" Fortunately (for your cables) Cirris Hipot testers don't apply high voltage and high current at the same time. They use high voltage, but very low current, to find problems in your cables, not create them. This keeps energy levels low. For an interesting look at what happens when you must have high voltage and high current together, check out this video:
