Dielectric Withstanding Voltage Leakage Current Limit Are you setting your DWV leakage current pass/fail threshold too low? The Dielectric Withstand Voltage (DWV) test, also sometimes referred to as a “Hipot”…
Does repeating the Hipot test damage your cable? Cirris cable hipot testers are designed to limit the current and the charge that is applied during the hipot test. * Consequently,…
How to Determine Creepage Distance for Connectors Creepage Distance/Air Gap: The Path of Least Resistance Electricity, like water, likes to travel along the path of least resistance. Looking for the…
AC Hipot Testing Hipot testing, also referred to as Dielectric Withstand (DW) testing, uses DC or AC high voltage to stress test insulation. This article focuses on DW testing using…
Mixed Matrix Hipot Architecture A hipot tester with mixed matrix architecture can save both money and space. Additionally, mixed matrix architecture provides long-term flexibility. The Traditional High Voltage Tester The…
Controlling High Voltage Ramp The high voltage* applied by your Cirris tester is a just one of the carefully controlled variables used to determine the dielectric withstanding voltage or the…
Top 5 Capacitance Errors in Cable Testing Have you struggled with capacitance errors? The stored charge in a cable or harness can create problems during testing. Capacitance failures may occur…
How to Hipot Highly Capacitive Cables A customer recently asked Cirris about a “charge error” that occurred during a test. This error has to do with capacitance in cables. If…
How to Protect Your Tester Cirris testers are built with a protection circuit to secure the internal circuits in case voltage or grounding is placed on test points. Voltage or…
Using Voltage to Detect Insulation Defects Here are some guidelines for using voltage to find insulation problems. Test Situation Recommendation When air gaps between conductors can be less than…
