High Voltage (Hipot) Testing

After (5) years of e-newsletter articles covering a wide variety of cable testing topics we noticed a number of newsletters devoted to subjects related to High Voltage Testing. This page was designed to bring together the links for 9 separate e-newsletters on this popular subject. The left side of this page will display an image of the 'Information Page'. Click on this image to be taken to the webpage where information on this topic resides. The right side of this page will show an image (taken from a video it relates to) and there will be a short summary of what is in the video. Click on the image or descriptive text to watch the video. (Note: In some months the topic did not include a corresponding video.)

Part 1 of Hipot Testing is a brief introduction to high voltage testing using the analogy of a water hose and how this relates to high voltage testing. Water is likened to current. The hose represents the insulated wire and a leaking hose represents current leakage from a wire. Take a look.




Part 2 of Hipot Testing, continues using the water hose metaphor to talk about what errors you would expect to see during high voltage testing and what each high voltage error represents.

  Hipot Testing and Components This video gives an excellent explanation of the sequence of continuity and hipot testing with Cirris testers and why it is possible to test cables which have components imbedded in them yet not have to worry about damaging those components during a hipot test.
